Hi all, Well... I'm surprised I've never heard of this before... and I don't remember it being discussed around here. Maybe it has and I just missed it. Adobe has apparently had for some time a free tool called Adobe Configurator (available for both Mac and PC) that allows you to very easily create your own customized Photoshop panels. I've tried version 4 (which on the main page says it works for Photoshop CS5 and CS6, but only gave me the CS6 and CC options in the actual program) and it worked great. I think this can probably do things that the AutoHotkey-based toolbars that have been developed in other threads can't do that easily. And yes, you can add an undo button. Anyways, here is the download link: Download Adobe Configurator 4 - Adobe Labs (CC users may also be interested in: http://labs.adobe.com/technologies/extensionbuilder3/) And a video: https://www.youtube.com/watch?v=fkNUsG9L0G0 Enjoy!
