As I have switched pretty much entirely away from using coot <1.0, I
have been noticing that undo doesn’t always behave predictably in coot
1.3.1 (using the Linux build from flatpack). It seems that backup
files aren’t written as frequently as I expect, so that clicking undo
can reverse more than the most recent edit to my model. As an example,
I just renamed and reordered some chains in my structure, saved the
file, and then fit a rotamer to density. I didn’t like the result, so
I hit undo - and the chains reverted to their previous id/order. This
was obvious, but other “oversteps” might not be so obvious and could
be missed.
Yes, that sounds about right. A lot of this sort of code was scraped and
written from scratch. I may have missed a few types of modifications. I
will take a look at the above recipe and see what's missing.
You can instead do a "Quick Save As" Ctrl-s which forces a save as (not
a backup).
King et al. has been all over my news feed today.
