Currently, empty shapes without any background fill are hard to grab and move around. You have to precisely click on the borders of the shape to select/move it. While adding text creates a central hitbox that you can use to select or drag, there can still be voids between the shape lines and the text. When users click on these voids, they expect to drag the shape around but instead they create a multi-select box.

It would be nice if the empty areas within the shape allow you to grab/select it. Shapes within shapes should be on a layer above (and can be easily fixed by sending the containing shape to the back), so this shouldn't interfere with moving these interior shapes around. Also, you can already hold ctrl to draw a multi select box and avoid grabbing a shape instead, so this shouldn't prevent people from multi selecting items within a large shape.

I like the look of having no fill or background on my brainstorming/plotting boards, but currently shapes without fill are a little painful when creating/editing these boards
