When using the paintbrush tool, it appears as a circle around a central +. When you left click, the central + disappears. Is there an option for the + to remain visible when left clicking?
Currently I am using a very large brush size and painting a very broad line beneath a much thinner one, and it is making it hard to guesstimate the centre of the brush circle after I left click and the + sign disappears. It would be much easier to keep the lines aligned if the + was always visible.
