Is there a tool to draw a ellipse, rectangle? If not, adding one would be nice
Yeah, I’ve been mulling over whether to add a shape tool and I think it’s worth the convenience it would add.
For now though, you can use the Box Select tool in combination with the Fill tool or the Fill shortcuts (Backspace for primary color, Shift + Backspace for secondary color) to create filled rectangles, and the Box Select tool in combination with the outline tool or the outline shortcuts ([Ctrl / Shift / Ctrl + Shift] + 9) to create outlined rectangles.
You can also use the polygon select tool to freehand an approximate oval, but I will add a proper shape tool that lets you draw mathematically defined ellipses.
