I'm basically wanting the ability to hold down a keyboard key and simulate clicking and dragging on the stroke eyedropper tool, so that I can sample colours quickly while painting.
For example, while painting in Photoshop, I can Alt + Click a colour to sample it, then continue painting. It would be great to have a similarly quick feature in Moho. Maybe the key could be a keyboard letter (e.g. Y) or, even better, be customisable in the Keyboard Shortcuts.
Example use case: I currently use a stroke to paint three basic colours; light, mid, shade. I then set the alpha to 20%. I then sample back and forth between my colours (and my alpha is maintained, which is awesome)! I quickly switch between painting and sampling until I have a smoothly blended look, which works well. But it would streamline the process to be able to Key Press + Click (or Key Press + hover mouse over colour + Key Release) to sample these colours.
Quick example:

I hope this makes sense!
Thanks in advance if anyone can help with a solution / workaround. I'd be extremely grateful!

Cheers!
