Guide descriptions

[Telpe]

To guide the user, most things should have a description.
Some elements have enough in a Hover Tooltip #8, but others require a more obvious guide.

So there need to be room for descriptions.

Perhaps a folded description. It would just show the start of the text (short description).
Unfolded it will show full description.
Unfold will not push UI, but rather be like a position-locked Hover Tooltip.

There could also be Guide Levels. So new users can have large presenting descriptions.
