[chimerax-users] undo/redo move?

[Tom Goddard]

Hi Oliver,

  I added undo / redo support the the move and rotated selected models mouse modes.  Also today I added a move selected atoms mouse mode that support undo with the Edit menu Undo and Redo entries.

There are several ways to do that, for example, matchmaker, fitmap, or align commands, move/rotate selected mouse mode, or move and turn commands with model option specified.  I think all those cases where one model is moved relative to other models should be undoable with our standard ChimeraX Edit / Undo... menu entry, although probably none of them are handled right now.  Is there a specific case you are interested in?

So I don't think that kind of move which is actually moving the camera, not the models, should go into the general undo.

However it seems like there is no undo/redo move functionality. I find myself using this a lot in Chimera, is there any possibility of incorporating this into Undo/Redo in ChimeraX? Basically adding the possibility to Undo/Redo translation, rotation and scaling?
