Greetings,
It would be nice to be able to select an ROI in the RoiManager's list in
such a way as to not instantiate this roi in the current ImagePlus; Maybe
Alt-LeftClisk. This would allow the user to query/modify the current
setting of the ROI as the RoiManager sees them. IJ.showStatus can be
called when the cursor enters/exits a widget.
Also the one option, and probably the only option, that I would use in the
right-button ROI list popup menu would be Properties, which is missing.
