I already did that. But I miss the snap feature as it allows to work
fast and precise...

See the attached file. It crashes in 100% of cases, if I rotate the
dashed line as shown in the video. However there seem to be two
different types:

a) slow rotation -> snap is indicated, then inkscape crashes but at
least creates a backup (that saved me a lot of time the other day!)

b) fast rotation, overshooting the target line where it should snap ->
no snap is indicated, it crashes with a different (generic) error
message and no backup is created (not good.)
