So far:
Easier moving (hold arrows to move)
Hold SHIFT to unlock from grid, let go to return to lock. Hold SHIFT + O to infinite draw (useful for making a random drawing)
Currently Adding - Hold K, J, L, or I to half nudge the tile in different directions (useful for grass

Currently Adding - Hold W,A,S,D to 1/4 nudge the tile in different directions (useful for grass

Edit update 1:
Control so far:
Arrows = move view
ASWD = 1/4 nudge to tiles
j k l i = 1/2 nudge to tiles
CTRL + Click = Delete Tile
CTRL + RIGHT click = Copy tile
Hold Left Click to draw tiles
ALT + 1, 2, 3 and 4 hides those layers
Shift: While holding, there is no grid lock.
O or Right Click = Overlap Mode (in case of glitch and cant place tile, press O or right click normally and you can then place a tile there)
Shift + o = unlimited Draw mode, useful for drawing a random batch of tiles =D

Hold Left Alt to nudge it 1/4 way diagnal =D
Current Functionality:
Auto save the name and extention of your last map file for qucker access =D
Ability to control RGB variables and name of user in an INI file as well as choose dark or light theme =D
