I agree that tabbed plugin windows would be great (it avoids a bunch of floating plugin windows). It’s one of the things I have in my top-15.
However, in this poll there is at least 10 features I prioritized even higher, so I couldn’t fit it in my top-10.
But I think that this is a feature that wouldn’t take much time/resources to implement, so I still hope that they go for it.
If so, it would be good if they also include a toggle button to have the option to follow track selection.
