My reluctance to add this, is I can only see "some" usefulness in a pvp setting.

I'd rather OSH remains generic and not suffer feature creep from trying to branch out to too many specific use cases.

That said if someone makes a good case as to how this could be useful in a general setting I could reconsider.

On a more general note, as it stands the only items on my todo list at the moment are:
- the strata configuration option.
- ability to position the different texts more freely and not only relative to screen center
(I can see the HUD-like concept but it bothers me that I can't place fx the target text anywhere I want relative to player text)
- check on VyneBono's issue with the slider editboxes not accepting precise increments (since I'm going to be messing with positioning anyway)

Despite I don't expect any of that to be too time consuming or difficult to implement, they're at a low priority atm while I work on other addons (and my leveling ), since OSH has no outstanding issues.

I'll try to put an option in for the strata for next release.

About your other issue, are you sure you're pressing <Enter> after typing into the editbox?

You should be able to type in the editbox that's part of the slider control directly instead of using the mouse to drag the slider itself.
Slider has a specific step (don't remember exact number atm) but editbox will accept precise numbers.

Hmm, ok the blinking is new, it was not doing that a few builds ago when I tested it.

For now uncheck "Show Resource" from "Appearance" Tab and I'll check it.
