Holy power counter

[Turel]

What i was looking for is an addon that tells me how many holy power stack i have on the spell icon inmy action bars. something like the range indicator, that displays a number, telling me how many holy power/combo point i have. i searched around, and i found weird i couldn't find anything like it, as rogues abilities have the same issues, they deal more damage the more combo point they have, but the ability icon in their bars doesn't display it, the player actually has to go look it up in target frame, as for holy power at the moment, i've to go look it up on the character frame, or use an addon that displays it, which as for as much helpful it is, it doesn't avoid the problem that i still have to look up somethingelse than my action bars.

anyone could help ? redirecting to something existing or work it out for me ? i honestly have no clue how addons work, at all, but this should be doable:

I'm asking for something like the range indicator on spell, but being a counter for the current number of holy power charges i have, inside the spells icon in my action bar(word of glory, shield of the righteous, inquisition, templar verdict, divine storm)

thanks in advance.
