hopefully this month some other additions by me will get some testing :-) (namely nested load undo crash and unaligned load at startup)
An AppImage that will work on just about any 64 bit linux distro with the patch for the undo crash in is at:: https://cinelerra-gg.org/download/testing/test_ubuntu16.AppImage and needs some serious testing because the patch contains an "unlock" which is always of some concern. It does not contain the fix for "unaligned load in bctheme" yet because I built the AppImage before this was reported and this patch only needs minor verification testing (and I forgot to do that too).
Those are relatively low-hanging fruits (if worked as intended), but something that keep me immersed in this specific codebase (and forks, yo!)
