Disable Tabs & Dual Pane?

the savesettings enhancement in 14.40.0002 should help scripts that deal with multiple instances.

That is: every XY will load a copy of the current files in the moment it is started, change them local in memory, and save with overwrite them when saving settings, i.e. on exit. And the last save will win, i.e. overwrite all previous saves.

I use multiple instances exclusively (I greatly dislike tabs and multipanes), and to get around that potential issue I have disabled "Save settings on exit (Startup & Exit)". Any time I intentionally change an option I save the settings manually. This has the added benefit of always launching a new instance in the exact location where I want it, rather than wherever the last one I closed was.

Same here. I'm not at all worried about using a second instance at least for the situations I would use it, which would typically be to open a folder in a specific format and layout. I've set it up such that a quick hit of a single key closes the second instance and I'm back where I was in the first instance. I certainly wouldn't be changing settings in the second instance or change settings period with a second instance up and running. A new SC to open a second instance of XY which would have a folder parameter like "goto" but would also permit additional scripts to load in the 2nd instance would be a very welcome addition.
