My friend and I would like to make an addon for blender as a coding project, but we don’t know what the blender community would like. We have some basic ideas of our own which may or may not have already been done, but would like to see if the blender community has anything better in mind. Thank you
Here are a few ideas that could help me personally and a lot of others as well 
- BGE Export to HTML5 (Very High Difficulty)
- Blender Character animations export to Spine File Format. (Figure out How the Bones Work)
- Export Character Animations to a format that cocos2d python library can load. http://python.cocos2d.org/doc/programming_guide/skeleton/skeleton.html
Here are a couple of different ideas for Addons or maybe some are more functionalities for current Blender. Anyway, I wouldn’t really say that these are the things that the Blender community wants because these ideas are basically related CAD like modeling and many times it has been stated that Blender is not built for that purpose. Also, I consider myself as hobbyist in modeling so some of the ideas are definitely not according to correct modeling when considering topology, etc. Nowadays, I really like Blender but because of my Sketchup background there are a couple of things that would be really beneficial in order to make Blender a little easier especially when thinking about modeling with exact measures (CAD like modeling).
- Change increment snapping to centimeters:
Now it is possible to set Blender increment snapping to meters but it would be good to be able to set the increment snapping also to centimeters. It is possible to model in centimeters but this requires always that exact measures need to be typed in and this slows down the modeling.
2.Offset edges:
It would nice to be able to offset/inset only selected edges instead of offsetting the whole face. I know that there is already an Addon that offset selected Edges but it doesn’t create the faces. Anyway, this may not be according to correct modeling in Blender. If I have understood correct, now this kind of modeling needs to be done with Knife tool but again there is problem that with Knife tool there is no possibility model with exact measures.
- Add construction Lines/guides:
In Blender it is hard to position something in exact measures. Therefore, it would be nice to have something similar as Sketchup has for drawing modeling guides and points for snapping. This kind of construction lines could also improve the use of Knife tool in case of modeling with exact measures.

Not sure if there something similar already existing that I will propose here. But when working in material, in node editor, we are forced to use a emission node to see clearly the texture which we are working on. Would be great, at least for me, some fast option with that purpose.
Something like “Save Cursor Position”…1,2,3…etc.
Enhanced 3d Cursor addon http://wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/3D_interaction/Enhanced_3D_Cursor
- 2D manipulator for UV/Image viewer (a really needed feature and so helpful for newbies)
a bone 2d picker would be nice , like the proxy picker from MAX HAMMOND https://vimeo.com/96737246 but with more automatic functions.
After creating the rig it should be possible to get custom bone shapes automatic depending on the
-active bone layer
the custome shape should be with same lenght like the accordingly bone.
for win it exist a small tool to http://www.chip.de/downloads/c1_downloads_hs_getfile_v1_47703482.html?t=1423583622&v=3600& keep a window all time in the forground.
Another solution comes from Bassam http://urchn.org/post/addons-for-empathy-2-proxies-and-a-bonus#more
i think this is a really nice addon …and much needed
The whole time you download a new version of Blender have to remove duplicate addons, which sometimes becomes tiresome work. It would be interesting one ADDON to do this automatically keeping the latest ADDON
This is great Tool! THX!
Some kind of viewer and debug nodes for material node editor. Its annoying as hell that you cant see value what certain math node is giving, same goes for procedural textures. Would be awesome to see in backdrop or somewhere how changes to values affect to image generated.
An UV packing add-on that can fill holes and packs better than default one?

Improve the outliner ( https://www.youtube.com/watch?v=ZYWdba2SMBs ) (HIGH DIFFICULTY)
-
Mirror action addon (for instance, if an action is a right handed punch, the mirrored action would be a left handed punch, or you could copy a set of keyframes in the dopesheet, and paste them mirrored) (Intermediate difficulty)
-
A pose relaxer keypress. In other words; currently, pressing CTL-E brings the selected pose towards the previous pose (when you move the cursor left) or next pose(when you move the cursor right). The "pose relaxer " (CTL-ALT-E or something else) would bring the selected bones toward the rest pose (when you move the cursor left) or further exagerate the current pose (bring it furhter from the rest pose) when you move the cursor right
-
An output of the viewer node. A lot of times, I scrub through the compositing tree from beginning to end, then the viewer gets to the point I want, but I forget to also tie the composite node to the end point, so, Just have he composite node connected to the output of the viewer, then, what I see in the viewer is what I see when I render
-
A way to disable text overlay of audio files in the VSE. When lipsynching, I need to see the waveform, I could care less about the name of the file
have a random object on startup
Groups with folders would be nice, though not sure if addon could do it!!
i don´t no if this can be done by a separat addon,
but it will be a hugh time saver to have a “Snap to the middle” as an Face Target.
Something like snap the normal or poke or similar…
improve sapling addon
Something i really would like to see is some kind of enhanced 3d cursor which not only saves Position but also Orientation. So that i can for example put the cursor to my selection and it saves the current orientation of the manipulator. So that it is possible to create a new Object aligned with the normal of a face, or change the orientation/rotation of the origin of an object, without altering the orientation of the Mesh itself. In form of a Python script it would probably need some kind of workaround though.
