Thanks for the patience :) We are also very excited to have a usable 
preview release soon. Scarlett is still working on the AppImage CI that 
should hopefully be ready by the end of august (maybe for next cafe) - 
otherwise we will look for other solutions to provide testing, because 
currently there is no other way to try it than compile it manually.

I will try to update the Phabricator status page regarding our 
refactoring progress, but currently the basic timeline operations (move, 
delete, group/ungroup) and tools work (razor, spacer), as does undo.
Effects / compositions are almost finished and mostly working (effect 
group not yet fully exposed). Clip markers, guides and proxy clips are 
also working.

What remains to be done is:
* effect compare
* timeline preview
* speed effect (this requires some special tricks in timeline)

Then we can start work on advanced trimming, and other exciting stuff.

So whenever we can provide a reliable way to test, the first steps would 
be as you suggested to test the timeline stability with 
move/cut/group/undo operations.

Best regards and see you soon in next café (21st of august)!
