Not quite sure how to describe this.
So in the context of the answer to a question -- see the Action List request -- I reorganised my actions into two groups: one to appear in the action list, one to house the others.
I have a few (five) actions that, because they're named with a trailing +, appear in the Toolbox right-click menu, and they got split up between the two groups.
All worked as expected. However... when it came to invoking one of the + items from the right-click menu, I got an error.
Restarting Toolbox restored expected functionality. So I'd guess that moving actions between groups doesn't keep them in synch with the actions that have been added to the Toolbox right-click menu?
Ah, I see. Bug confirmed: the action is not found after moving groups. Fixed for the next update (check your email to download the fix).
