In Qgis 3 is this useful set of tools to create regular shapes like squares, rectangles etc

If you want to make a regular shape bigger then when you drag a side out there is no constrain to ensure the shape is maintained.

A modifier key you can press while dragging the side to ensure it can only be dragged in or out, not sideways, would be useful.

If I understand correctly, you want the equivalent of a resize tool?

I can add it into https://github.com/qgis/QGIS-Enhancement-Proposals/issues/106

I'll try to explain more as this comes up a lot when I use the new geometry tools to draw rectangles, circles and so on. Essentially I want to be able to resize while maintaining the existing geometry. At the moment if I want to resize that rectangle using the node tool, there is no way to constrain the direction of the dragging of a corner so you are only dragging in one direction at a time.

That is the comment about how to resize a rectangle. You can imagine it would be a lot harder to resize a circle one node at a time with lots of nodes, to say nothing of maintaining a perfect circular shape.
