Ultimately I think this would just be a bandaid over the root problem - Perspective's editing logic is complicated, so sometimes (most of the time...) it doesn't select the view you're editing, when it's supposed to.
Fixing that seems like the better answer, but I can see some merit in something like IntelliJ's little bullseye widget, at the project browser level instead of attached to each individual resource editor...
Yes sure this could be very convenient ! For very large project looking for the opened views or otherwise ressources in the project tree take Times and is quitte frustrating
Yes and time to time when you save project the view tree collase and it is really hard to find the view again specially in complex view layout.
Also it is nice if we have related view path addressing.
This is definitely one of those little daily frustrations. Particularly when working with a project where there was no thought about naming and hierarchy. Has my vote!
