First off - I really REALLY love this app. You guys have put together a pretty fantastic product and are really good about getting back to customers, and I really appreciate that.
Maybe it’s a newbie thing, or that I’m so used to working in Illustrator, but a few small features that I would add to my wish list would be:
I’d love to set vertical & horizontal guidelines at specific locations so I can visually see for example, how far out a tail extends on an “e” relative to the apeture of the eye… Rather than having to draw a line in.
I would not use guidelines for that. Either quickly measure it by clicking and dragging with the measurement tool (shortcut L, or activate it temporarily by holding down Ctrl-Opt-Cmd), or, as Georg points out, make a selection and read its measurements in the grey Info Box (Cmd-Shift-I).
