One of the most powerful tools in BIAB, if not the most powerful is Partial Regeneration. (I strongly encourage those who don't know about it, try it)

Currently there are 3 issues that I would like to be addressed.

#1 There are two pop up dialogs, Modal and Non-modal. Combine the two to a non modal panel item (tab)

#2 When you generate a part of the track, lets say section somewhere in the middle - track gets semi-frozen. You can still do partial regenerations to segments on the left and the right but it will not pick up new changes in those. Proposition is to only semi-freeze the sections that went through partial regeneration process, leaving all other segments "unfrozen".

#3 Undo sort of works, but I would like to be able to save some regeneration variants that I thought were interesting, as you can lose regenerations and there is no good way to get them back. For example implement A,B,C variants so you can audition side by side and pick the one that fits better. This is important one and needs thorough discussion.
