Desktop app: Version 1.0 (2343)
Steps to reproduce:
Open two or more notes in a tab structure and re-size the window larger than the very small default Panda open size (at least on standard iMac monitor).
Then open or create another note in its own window (which, by default, is quite small).
In the menu, select Window > Merge All Windows
While the “singlet” window does properly merge into the tab group, the tab group window resizes to the tiny “singlet” size.
I would have expected the opposite - that the “main” tab structure window would retain its size.
