Ctrl+z undo isn't aware of currently focused tab

[subsoap]

If I have a collection open, edit some text in a script, go to a collection and move an object, go back to the script and press ctrl+z instead of undoing the text in the script it will undo the move of an object in the collection.

This is the most productivity killing issue for me right now. Keep trying to undo, it not working, then realizing it undid stuff in a few other files.

Ditto on this! Not being able to see what you're (un)doing is a huge problem.

I propose two possible fixes (maybe one of these is lower hanging fruit than the other)

• It would be more tolerable if the undo forced me to view the tab I was undoing something in so I at least had a hint at what I just undid, since right now if I undo something in a different tab I have zero UI feedback.
• Or, have "user changes tab" append to the undo stack. It would be annoying but at least it would be intuitive and give the user clear feedback on what the undo just did.
• Or, my preferred option: rather than having one universal undo stack, give each tab its own undo stack. When you hit CTRL+Z it only does an undo in that tab.

Any of these would be acceptable, and would be 100x better than what we have right now. It's soooo annoying to re-introduce a bug you just fixed because you just undid the fix and didn't notice.

It doesn't inspire confidence that this issue is 3 years old...
