TO SAVE A LOOPING GIF:
The timing settings let you save looping gifs of any length (up to 16s). When ready, change the gif_record setting (under Timing) to true. This will reset the loop, clear the display, disable the menu, and start recording. When it's finished a little popup will appear with your gif. You can then right-click and save that popup gif.
