Apologies if this has already been discussed somewhere but I didin't see it in the 'enhancements' list. First off, love this app!
I use two additional monitors most times, but when I unplug and then come back, I have to reposition all my windows into the respctive monitors and resize them. This is already made much easier via keyboard using Spectacle, but I'd love to be able to save a particular "layout" (ie. 'two monitors' or 'laptop only') so I can reposition everything at once and not have to repeat that exercise everytime I plug back into the external monitors.
Out of scope for this app. Something like https://cordlessdog.com/stay/ might help you though.
