Today's update adds two power-user features, which are mostly hidden for now: 1. Pressing F10 while editing a solution will reload it from disk. This will only be useful to players who are using an external program to edit their solutions, who previously had to restart the game to see their changes show up. 2. Pressing F10 while the GIF recorder is open will switch it into advanced mode, which allows you to manually override when recording starts and stops. If you hit F10 after the solution finishes recording it will default to the automatically detected start and stop frames. If you hit F10 before the solution finishes recording it will cancel recording immediately but require you to set the start and stop values yourself. If you have any deep thoughts about these changes you should email me (zach@zachtronics.com) and let me know what you think!
