I am just learning blender and python and thought I would have a go at this just as a learning exercise.
ziel has obviously produced a really good solution. I juts did a simple counter to see how it would be done and learn. I then had the idea that as well as just showing the number it could be used as a line number and reference a text block.
This was quite easy to implement once I had a countdown script.
This video shows my implementation, the new text bit starts at about 1:30:
It is quite simple but allows quick and dirty subtitles. The video itself has a text overlay done using this plugin. The text is moving and scaling slowly just using standard blender anim.
The code is here and perhaps ziel can integrate in to his better counter addon. I am happy that you use the code as long as the final plugin is GPL as the OP stated it would be.
