Hi there!
First of all I want to thank you for the absolutely fantastic program you've created. I feel I have no need to wait for the Photoshop on Ipad anymore. I can't draw a decent line with Procreate so this program has been my saviour.
My suggestion, and I hope that I'm just too stupid and this is already in the program, is that in Photoshop you can select a layer by pressing control and tapping somewhere on the canvas where there is content, line painted, text etc. This is really helpfull especially when arranging things on different layers really quickly.
Thanks again
