Plain and simple. Add a shortcut that switches between "Tile Mode" and "Object Mode" so you don't have to manually select a tile or Object category to swap between each. This makes switching a bit more convenient imo.
There should also probably be some kind of text telling you what mode is currently active (similar to the "Autotile Mode" text next to the Undo-Redo buttons
