While the web (besides time machines) is styled much nicer than ever, this does not always mean, it’s your style, nor that user experience is much better for you.
In my spare time, I have created some (hopefully) handy scripts and styles:
A slimmed down StackExchange
To get rid of the distracting side bar on some of the StackExchange sites, I have created the StackWatchers user style. This also improves the reading experience on narrow windows.
Better UX with NxFilter
To have a better visual distinction for blocked requests by the DNS filtering tool NxFilter, I have created NxFilterColorizer, a user script that colorizes the table row depending on the block indicator text. It also applies a CSS class that allows further styling with a user style.
Global wait indicator
Having a wait indicator is often useful. The waitin.user.js script gives you a global wait indicator for any website at once. (This is in ALPHA state, use with caution).
