Map-Saving/storage increase

[jingseng]

I'm more than a little tired of losing all my maps, all the time. It seems more than a little odd that we lose our map-reveal data when we have EXPLORER goals -_-. It's a small thing, but please allow us to retain all our maps rather than "3 most recent". If it is stored server side, please switch it to client side, or some such - as it is, many of the maps are available online with rares and explorers revealed. It is a gameplay nuisance to lose map data constantly, and be forced to resort to out-of-game maps.

Along with that, adding custom map notes that persisted would be nice. I'd like to be able to mark rare locations, explorers, secret doors, traps, or even make notes about which branch in the dungeon should be taken first.
