I’ve searched around a bit and not found anything for this. I often switch between single and multiple column layouts, depending on the work. A common use-case is when I need to really focus on one file, I go back to single column, but when I’m done, want to go back to multiple. But I lose the ‘positioning’ each tab had in one of the groups. Is there any way (a plugin perhaps?) for ST to remember which tab was in which group?

Thanks,
Dave
