Almost what I was looking for – Battle Map 2 Review

I created my own spin-off version of DnD to play with a group of friends.. the game turned out well, but everyone complained about the lack of visuals. I found this app, and was thrilled by the idea I could create the map, and host it on my TV. Talk about epic visuals! To my dismay, I have discovered one small flaw in this app, which renders it useless for my game. Our game is a "room by room" grid system. EVERYTHING is perfect on this app for it, except the visibility. There's no way to make each grid work as a room, while concealing the surrounding grid tiles. I tried using all kinds of objects, block LoS, but to no avail. I even tried removing range of light source, but that just makes the character disappear entirely. If it's set at the minimum (1) then it reveals all 9 tiles around you. Hopeful suggestions: Allow a more friendly tile-to-tile approach. Allow LoS to be more concisely controlled. If anyone knows a way to get around my issue, I would love to hear it and would instantly give this app 5 stars, and would have everyone in my group purchase it!!
