Actually, I think the slight deviation from normal undo behaviour can be
made even less intrusive depending on the number of "new-branch steps" are
permitted before the original history branch is deleted.
Even limiting this to only 1-2 steps would in most cases solve the problem
pointed out by Felipe while still remaining totally non-intrusive.
This also increases the chance of someone stumbling across the function but,
of course shouldn't prevent us from clearly documenting it.
Finally, also including selection-actions in the undo-history (like in
Blender) would also enhance it very much, although that's probably a
different discussion. *Example*: In Inkscape, select 5-20+ single path
nodes, shapes or similar and then *accidentally* click on the canvas or
somewhere else in the shape and poof, all nodes are unselected. As the
number of selected points increases, so does also the fear of missing the
next point with the resulting in having to start the selection procedure
again from the start.
Another way would of course be to allow clicks inside the shape or on the
canvas without de-selecting the currently selected points.
*Furthermore *Shift+Click
on a node currently toggles its selected state. However,
Shift+Drag-selection does only select nodes or shapes but does not toggle
between the selection states. In my daily work, I actually do this quite a
lot if I'd like to select all nodes or shapes in a particular area of the
canvas, then I do a Shift+Drag selection again on a few nodes inside the
first selection to exclude them from the selection before I finally perform
some action on the remaining selection ( - typically moving it to a
different layer below to avoid having to do the detailed selection again for
the next action.) But again, this is another discussion... :)
