As my (and other's) studying method requires a lot of colours, I would like to be able to change the highliter or pen colour faster. So, I'm suggesting something like a detachable grid for colour selection or an option which allows me to visualize more than 3 rapid colour choices in the main bar (for instance, hiding through the settings menu the unused tools to make room for the ones that I use more frequently).
In other words, I would like to customize my tool bar and make it more efficient to meet my specific needs. Is this possible?
Thank you in advance!
