Yury's RuneDisplay provides a replacement for the default runebar. It's easily configurable with the new Config GUI, type /yrd config to access it. Features including (but not limited to) moving, resizing, fading when not in combat, clear cooldown (with or without numbers).
On purpose not included: disease tracker, proc watcher, runic power.
Because of the rewrite, settings are reset to defaults, sorry. Also most of the localization needs to be redone. If you speak one of the languages WoW is localized in, please don't hesitate, leave a note.
