I have read different threads regarding a feature request for custom icons.
I would like to also add in how great it would be to have more control over tile design:
Rounded corners (with control over how much)
Icon placement (left, center, right)
Label left/right of icon if icon is off center
And of course, custom color icons.
I will add, I think Sharptools is amazing (I’m new to all of this!), and thanks to all those who work on continually improving it.
