I'd like the amount of map squares to be altered to equal 4 feet instead of 5. I found while trying to customize the map settings in roll20 that it was not easy to accommodate squares equal Lane 2.5 ft for tiny creatures. The grid settings in roll20 does not allow for decimals. Calculating square space for tiny creatures would be made better if squares for calculated in increments of 4 feet instead of 5 feet. I recommend to fix for this, for instance, tiny creatures occupy two feet, small creatures occupy for feed, medium creatures occupy six feet, large creatures occupy 8 feet, Etc.
