I'm really glad the new drawing mode is implemented and it works surprisingly well.

The default shape color is green and if you use the green board themes, the circles and arrows are not that visible. Also it's possible to prefer other colors, for example whenever I use arrows and circles on desktop, I always use the red color, no matter what board theme is set.

One way this could be implemented is to add a simple setting in the board/game settings. For example, this would work really well with the Puzzle screen in my opinion.

Implementing this the way I imagined sadly doesn't make it possible to have several different colored shapes on the board, but I'd say it's not that important on mobile. Having the option to set a custom default color for the shapes on the other hand could be useful.

Let me know what you think, if it's a good idea or not, if it's possible to add or not.

Thanks a lot as always and keep up the amazing work!
