Offline capabilities

What Feature would you like to see included within TaleSpire?
I would really like to see some sort of offline feature available eventually. Something as far as being able to download all (or specific sets) of the content to be able to make maps while offline. Or simply being able to load the slabs while offline would be amazing.

What situations would this Feature be useful?
This feature specifically for me would be amazing due to me being in the Navy, I spend a large portion of time out in the middle of the ocean with no internet capability. I run D&D games for my friends on the ship while we have free time and I’d love to be able to use the maps I create for that group while we are out to sea.
