Dock and Lock Canvas Windows

[T_Willins]

I set up my canvas how I want it, but I will sometimes undock or auto-hide the canvas windows (Results, Configuration, etc.).  My suggestion is to add a Locked Dock as a selection that will allow for resizing, but not undocking.

I often undock parts I don't want to undock by mistake 😂

A locked dock would be helpful to avoid that.

This would be great!

it would also be great if Alteryx could remember the size that I set various windows - every time you switch from one tool to another, you need to move all the sizing for the sub-windows again.
Example here is the input tool - dragging down the divider to see more of the input tool config.
