 1. Tool window is modal (can use other tools when tool window is open). Is
 that really necessary? (also the case for some other tools, like Random
 Selection within subsets

 2. Tool window is replicatable. Click 10 times on this tool, will have 10
 tool windows.

 3. Finally, if the layer is switched off after opening tool window, throws
 an error (also the case with Random Sel within Subsets and related to
 modality):
