I made a fork today that:
- Fixed crashes with Selection Tool + Move Tool
- Removed the annoying popup save dialog
- Defaulted snapshot interval to 1 (instead of 3)
- Nicer output file names

Feel free to yank some/all of the new content from this and bring it into the main project.
I also wrote a post processor that will collapse sequences of identical output files. It will also rename things in proper order, letting you hand-delete bad recorded frames (such as an accidental paint fill). It's still pretty rough on the edges (wrote it today), so I don't have a link for it up yet.
