I would like you to make it possible to mov the order of the colour filter - this would help so that I only look to the colours I use.
Also, it could be nice to be able to label the colours, so that students consistently use the same colours for the same concepts ‘pink = facts’ ‘green = questions’ etc.
Finally, if it was possible to not see the colours that you don’t want to use that could be helpful too, so that I don’t get confused between which blue I use
I like to keep things really consistent!!!
