I love this feature, however, there is a small problem that could be improved. When you left click, to put down the first stroke, then hold shift, make your line, then left click to make the complete stroke, it re-imprints the first stroke again. If you have any spacing and height information, it can be quite obvious that the first stroke was hit twice.
Also is there a way to turn off the tool tips? When you shift that tool tip overlay can be in the way of my view when painting.
