01: Lock Ratio when scale; 02: Multi tabs for working space; 03: Short cut for Design/prototype mode
01: When I wanna scale an image or icon with a certain number I need a lock ratio check box to link the width and height.
02: I prefer to working with multi tabs for the documents like Photoshop/Ai....
03: I prefer a quick change mode between Design/Prototype
Please do break these down into individual requests. Just as a side note, we now have a new quick change shortcut – Cmd-Tab – to shift between the two.
