Summary 💡

Improve the visual editor by adding the feature to resize components through a resize handle (inputs horizontal only, data grids vertical). It should be extensible enough so that we can share the logic with other components. Bonus points if there’s a way for custom components to integrate resize handles as well.

Closing, as basic resizing functionality has been merged.
However, even though the current resizing features are sufficient I don't think they're complete enough. All components with variable height or width should allow those properties to be resizable with handles, as well as their spacing.
I've created an issue for a refactor (#712) that should make it easier to improve the resizing behavior. Will create 1 or 2 issues for improving the resizing of components and their spacing too.
