I like it a lot but would it be possible to make right-click on the top colour pads just select that current colour and not generate a new set of 6 colours as well.

The reason is that currently if you see two colours you would like to use there is no way of going back to the 2nd colour after you have clicked on the first.

i have added this as a wish in our bug tracking system.

here is the link:

thank you for the wish , i will fix it most probably for the 2.3 release.
