Sort maps alphabetically

At the moment Caltopo displays maps in the reverse chronological order of last access time.  That works great for the top item but is confusing otherwise.  When I need to pull up a map accessed a few months ago I need to read through a list sorted in no particular order that is useful for the situation at hand.  On the desktop app maps can be sorted in alphabetical order with a single click but that is not an option on Android.  Would be great to be able to always sort the maps in alphabetical order.  The ideal situation would be the 2-3 accessed maps at the top, and an alphabetically sorted list below.
