In presentation mode I can draw on the slides, which is very helpful to make presentations a bit more interactive. The default color is red, and I know that I can change that color somewhere in the preferences submenu. For that, however, I have to quit presentation mode. I would like to be able to rapidly switch between a small (~5) number of colors directly in presentation mode. Ideally with a single click. Having several colors would make my impromptu in-class drawings much easier to understand. I admit that I am not really sure how a good user interface for this would look like. In the presentation mode itself, having several copies of the pen icon for the different colors would be ideal. Then, for me, just having the standard primary colors would be sufficient, but others will certainly want to assign other colors to the pens. Also, 4 colors for me is fine, but in general one would probably want a configurable number of pens. Not sure how to fit all this into the preference dialog. Reproducible: Always
Limiting the color to the primary colors only is not a good idea because the color we have right now is already configuratble, so you'd have 1 configurable and then right, green, blue [black, white] which would be weird to not be able to configure. I guess if we want to go the full way here we just need to add a list like the one for annotations, and while at it, since the same engine for annotations is used for the color in the presentation mode one could allow for configuration of width and opacity too, which would be for free. For the UI one would have to add the multiple tools in there using similar code to the one we use for the annotation bar. Would need to see it before being able to say if it's good or horrible :D
