These are really great changes. I haven't 100% adapted to the latest with Gimp but hope to get more time in for play. The broad changes in 2.10 were driving me crazy on a recent, more serious comic art project, so I reverted to 2.8.
Since that time though, I'm getting used to the changes, and the non-destructive techniques are really appreciated, especially compared to the old contingency methods I was using like saving backup layers.
Gimp is, to me anyway, almost a completely different app now.
