I was wrong in my previous post: you can install v0.52 from blender's interface providing you select the zip file and don't uncompress it before. It seems it has some side effects that I've docmumented in the initial post but nothing too serious.
I can't work on the plugin today but here are some plans for this week-end (and later):
- allow user to choose behaviour of Status Notification (blocking, non-blocking, none)
- pdf plugin documentation
- automatic material renaming during export with ascii characters only and no spaces
- support for relative paths and paths containing spaces
Please fell free to post any realistic suggestions on possible plugin improvement
