- UndoRedo for Add/Remove/Clone/Move Frames - Set functions for frame changes (both on canvases and Global.current_frame) - Removed unneeded signal methods and put multiple signals on one method instead (for example, add and clone layer button signals both connect to add_layer()) - Fixed bug where, if you opened a .pxo file with multiple frames, the remove frame button would be disabled. - Probably other small things that I'm forgetting to mention
