Thank you for this update. The interface stopped flickering on my machine. I'm one of those ctrl to activate the color picker people. I rest my hand on my desk and my index finger by the ctrl key. Other than that, Pixelorama fulfills my wish list.
We are glad that you like it! The feature is a bit hidden at the moment, but it is possible to hold Alt to activate the color picker, when you have a drawing tool selected. In a future update we hope to make this keybinding configurable by the user as well.
