Can this window be made taller?
The strange thing is I think it’s now smaller than it was last week. 
None of the edges seem to drag - which is what I’d have expected. It only seems to resize to the open masks … and I want to be able to see what’s in each mask (when there are more than one).
Googled without success.
Looks the right size to me.
I don’t think you can do what you want.
See if others have put it as a feature request and give it a vote up. Or create the request if it’s not already there.
I think you can rename the masks which would help
That i do (tho not in that screen grab example), and i even name the additions/subtraction in case they need later scurrie adjustment … or with complex ones I’d totally lose track of what was happening.
I’ve realised that one can’t have two, or more, masks expanded simultaneously, to show all their additions/subtractions that’s not possible … and that I’d really like.
Something akin to the Photoshop layes palette would be great. Expand/Collapse at will.
