There are a lot of feature-request's on Meta that seem useful. I've gone through some of them, and made one userscript to add some, or all of them:

Features added:

• Fixed Topbar
• Unfade low score answers
• Move show more comments link to top
• Ellipsis after long names
• Rename chat tabs
• Move start a bounty to after the question (instead of after comments)
• Make the bounty box draggable
• Fade out vote signs on deleted answers
• Replace > bullet points with more normal ones
• Differentiate between employees¹
• Remove exclamation mark on error

In this script, I've made everything optional. You choose what you want - if you hate the fixed topbar (which it seems a lot of you do...), disable it!. The options are saved in a cookie².

The script

It's on Github Gist over here.

Please post any feature requests (along with their meta link, if applicable) and bug reports (along with any errors in console, if applicable)!

I've only tested it on Google Chrome - please tell me if you find any compatibility issues.

Clicking it will delete the existing cookie and show a div for you to choose the options and save the cookie again. Annoying thing is you have to set the cookie on every SE site you visit (for now...):
