- Health Bars - Give us options (checkboxes) to hide the health bars of friends and enemies. The ones I'm referring to are the ones over their heads.
- Sounds - Allow an option to mute all game sound without adjusting the sliders. It's a pain to reset my sliders all the time.
- Name Colors - Allow us the option of changing the text colors of names while in outposts. Sometimes it's hard to read names and titles against certain colors. Not enough contrast.
- Chat Tabs - Customizable chat tabs. Self explanatory. No more watching my chat scroll by because of loot spam when out in the world.
- Class, level, and location in guild display. - Pretty self explanatory. More info on guildies in the guild display. Maybe also show how much faction they've donated as well.
- Sorting Heroes - One of the things that annoys me is that I can't sort my heroes. Be it by profession or by name. And if you're confused, I mean the drop down list of where you choose them from.
- Keyboard controls for dialogue boxes. - For instance, when you press F12 to log out, you see that you can press the corresponding letter for what action you want to do (Y = Yes, C = Character Select, N = No). The same should be on when upgrading armor pieces or whatever. Allow us to use the keyboard instead of clicking a million times.
Edit:
Good suggestions by the replies. Custom name colors for friends, guild mates, and even maybe for people you've ignored (so you know when they're stalking you and in the same dist, lol, it's happened to a friend of mine on GW). And custom radar dot colors for them as well to match.
