It might be quite valuable to be able to choose a pattern of how multiple opened notes are shown in the main window. Right now the way it works is that every next opened note is added as a vertical column (sort of) and if you want to have 10+ notes opened, you have to manually reshuffle them just to be able to read them (the desktop space is not used efficiently).
It would be nice to have predefined options to change layouts. more specifically, I mean something like a “grid” when the number of rows and columns is kept the same, or, perhaps considering the monitor/window ratio:
4 notes: 2x2
6 notes: 3x2 or 2x3
8 notes: 4x2 or 2x4
9 notes: 3x3
Etc.
