This would be a very useful feature. My teacher use filled shapes all the time during lessons and it's a time wasting task for me - while followig the lesson content - to always fill them out manually
It's been some months... Can we please get this feature? There is times when you really have to fill a shape, like wanting to fill a background shape to stay behind a table you just made or making diagrams. It is very time consuming to stay and paint with your brush untill you fill half a page of one color.
