v.1.2.1 is now available!
Biggest change is the new keybinding system that allows more flexibility with key configuration, and should make additional features easier to implement. Also fixed some bugs and added other stuff, see below. There was also a 1.2.0b update that fixed an issue with loading scenes if you missed that.
Added: New keybinding system. Read help file for more information and also be sure to report any bugs or issues if you find any.
Added: Ability to rotate selection clockwise/counter-clockwise when holding Shift key and pressing Q,E.
Added: Hold space in tileset tab now allows panning of the tileset if zoomed in.
Added. Option to move crosshair to an object's origin point found in an object's menu when right-clicking an instance.
Added: Rename object points except for the origin.
Added: Subdivide tiles into columns and rows.
Added: Pixel resolution and window size can be configured in the settings.
Fixed: Sometimes applying a UV to an existing tile or copying the UV from a tile would accidentally draw or erase tiles if the mouse was dragged in the process.
Fixed: Moving the origin point of a prefab object would cause issues when rotating tiles immediately afterwards.
Added: Experimental normal map and height map image generation of prefab objects, accessed by right-clicking objects in the Scene tab.
