Photoshop-like direct editing of widget IDs in the outline
It's obvious that Justinmind is designed to mimic some of the better features of recent versions of Photoshop. A feature that I much appreciate on Photoshop, as I am a "Layer Mayor" (http://photoshopetiquette.com/) is the ability to easily rename layers, especially after cloning a group. Being able to do so without having to click on the outline, then go all the way on the other side of the screen in the properties panel to edit the ID, then back to the panel for the next one.
I've created a macro using Keyboard Maestro that does some of the back-and-forth for me, but it's nothing like having the IDs directly editable in the outline.
