PredatorBar is a small addon which provides some game-relevant information at the bottom of your screen, including:
XP-/Faction-bar (shows your XP if you're not max-level and will then switch to your watched faction, hovering will displayed detailled information).
Guildmember (shows online member, shows a tooltip, when you hover this field, opens Guild-tab when clicked).
Friends (shows online friends, opens Friends-tab when clicked).
Latency-/Memory-/FPS-display (shows tooltip with detailed Memory-information when hovered).
Shaman Ankh-watch (this seems broken atm).
LFD (click opens the LfD-menu, switches to queue-view, when you entered a dungeon-queue displaying the wait-times on hover).
Please note, that this addon is created to fit my very own needs, it is only published here, because I was asked for it in the comments of my oUF_PredatorSimple.
I will not include features I won't use. But of course you can request things, perhaps your requests are so cool, that I will consider them!
There is NO ingame config, so if you want to alter something to your needs, you will have to have some basic Lua-knowledge. The source code is pretty straight-forward, no mysterious hacking in there. You will find, what you're looking for.
