Feature Request: Saveable Town Layouts and Army Compositions

Pretty simple really but I would like to see 2 - or even 3 - memory slots in the town layout tool to store village layouts.
Most people like to switch between a farming and trophy focus from time to time or even try different approaches and this would make the whole process so much easier.

Likewise for generating armies, using the same principle to retain a couple of pre-saved configurations would really help.

Could be an unlockable feature with gems but would be nice if it was free :).

Savable army configurations are ruled out.

I had the same idea about saving town halls. It would make things much easier especially when switching from a farming base to defense base or to switch back to one of your old bases. Great idea!
