[ENHANCEMENT] Weird Flashing when Editing Unmodifiable Tile & Bad Location of Error Messages

[jadeandtea]

Describe the current behavior of what you're trying to improve. If your enhancement request related to a problem, please also describe the problem.

When the user has selected an unmodifiable node on the tree, the user should not be able to edit any of the tiles on the board. When the user tries to do so, the background of the tree system flashes and an error message is printed at the bottom left of the application.

Describe the improvement you'd like

It is a bit strange that the response to the user interaction appears so far from where the user interacts. I feel that the flashing is very distracting and could be removed altogether. The error message is crucial, but appears a little too far; if it could be relocated to below the board, I think that would look better. It would make sense to keep the error message option by the tree as well, so that if the user makes an error by the tree, the error would show up there.

Describe alternatives you've considered

An alternative for the flashing would be to make the cell the user attempts to modify flash red, but I think it would be too distracting. There's no harm in giving a shot tho.
