Normal View and Grid Cell View
Except buttons 'grid', 'grid 0' and the sticky button all other gui elements here are used for the grid configuration. This is, what the tkinter commands grid_rowconfigure and grid_columnconfigure do.

Button 'Show' switches to 'Hide', when it's pressed.

And it shows the grid cell view.

At the bottom of the grid area are frames, for each grid cell one. Their border shows the position of the grid cell. Their background color lets frames of the default background color become visible. And there is a Button-1 event bound to them for positioning new widgets.
