By default, the statusbar is positioned below the playerframe. The statusbar can be unlocked and moved around (and resized) freely.
Once your mana regen has started again, the statusbar will show when your next mana tick is supposed to happen.
After spending mana, 5 seconds have to pass before your spirit-based mana regen resumes. This is how the countdown looks.
