I’m using the split editor panels and despite clicking on the left panel (side-by-side view), if I select a new file it always opens on the right panel. The left panel is not locked, but it just automatically seems to open anything new I click on in the right panel.
I think there was a preference somewhere for that, but I can’t seem to find it now.
The behavior you’re describing seems to be desirable,
If your left panel is the draft and the right is notes.
Probably you should recheck the settings in See View: Move Focus to
And experiment with changing the options.
