We should check if this decreases performance and increase memory consumption -- IMHO the old binding should be removed. I don't know if this possible (or if this is an issue at all...)

Oh, I missed that the binding will be added every time. One solution is to revert this commit and check if currentlyEditedEntry is not null in adaptVisibleTabs(). Or, keep this commit but add a new boolean to track if the binding is registered or not.

I was hoping for another way. Also to apply for the other binding creations in the same method.
