Issue Description

Many config settings already have hover/titles, but they could use some improving, and some settings do not have any hover titles at all.

Titles must contain:

• Setting description (adding warning for advanced or sensitive settings)
• Valid value range
• Actual attribute name

We can find most of the lines with this regex: title=\{_\("([^()]*)"\)\}
