Index filtering

By default the index shows the content folded. Opening or closing items is remembered while browsing the documentation. To quickly find items use the input filter. The filter will display items that could be invisible within a folded item. When the user types in the input field, let us say fo, the index gets filtered with all the entries that match those two characters. So the index will display three matches: Fonts, Footer links and Footnotes. Those three entries were all folded within their sections:

The TOC on the right side

The Table of Contents, displayed on the right side, spans itself to the right border of the browser to display long items, improving readability.
