Roll frames look cool WHAT ARE THEY

Is there a mod that can display the progress of the GCD as if it were a cast-bar? I'd like to put something like that next to my TellMeWhen icons so I know when to hammer the button.

I know Quartz has this, but I was wondering if there were any alternatives, since I only want just the one function out of Quartz's entire library, and Quartz's display itself is quite small and difficult to read.

AzCastBar can do this, and you can disable the other modules 'cept for the GCD bar.

I use BarTender for that.
I made an Action Bar consisting of one single button, with Clickthrough visibility properties.
The spell-icon in the button is an instant cast without a cooldown (Water Shield, in my case, but any Tracking will do, for instance).
The button has the greying-out clock thing that normal icons use to indicate GCD progress (and addons like Cooldowncount or OmniCC will apply to this icon, in case you want a numeric counter).

EDIT: As I read your post again, I see I missed the "as a castbar" part. You're probably looking for something different than what I described.

Utopia is what you're looking for. Great and tiny addon tbh.

Auracle can do this as well. Utopia has talent scanning so you know if a buff/debuff is even available in your group and it is pretty well configured out of the box. Auracle lets you pick which buffs/debuffs you're watching so you can use it to do the same thing as Utopia plus watch dots on the same compact frame. I found Auracle useful as I was playing my feral kitty so I could watch for raid debuffs that impacted me (heart of the crusader, sunder, etc) and my own debuffs (mangle, rip, ff) on the same compact frame. I also have a frame setup to show my important raid buffs when I'm in a raid so I spot ones that I'm missing. Either of these two are good solutions.

I'm curious as to if there are any lua config buff frames. I like keeping my memory on the low end and I don't mind coding from time to time. Any suggestions on there?

Does an addon exist that puts the cast time of a spell on it's action bar button? Like what OmniCC does for cooldowns but for the cast time of a spell. This should include any short term haste and cast time modifying buffs I might currently have, like Heroism, Borrowed Time, Serendipity, Wrath of Air Totem, etc.
To clarify: I want to know the current cast time of a spell before I actually cast it.

DrDamage can put total damage/heal on spell icon.. when mouse over u can see the cast time... idk if you can put cast time instead of total damage or heal

That was the first thing I tried, unfortunately DrDamage does only display damage, heal and mana values, no cast times.

I'm fairly sure the cast time for spells is in the default tooltip. I know its displayed in my tooltip, and I don't have any addons other than DrDamage that would effect it. I'll double check, and if I have an addon that I forgot about, I'll let you know.

If you're talking about a program outside the game, Rawr does that for you.
