Give us a clear and concise description of the problem, and what you expect to happen
Created a focus frame (for Polymorph) using /focus command ... entered /script message(GetMouseFocus():GetName() to get the type of frame .. it returned "FocusFrame"

Went into settings of OmniCC, rules, enabled "Unit Nameplates" and added FocusFrame on a new line into "Patterns" field. accepted, hit okay.

Cast polymorph and countdown appeared on unit frame but not on FocusFrame as I had specified.

OmnicCC and WoW versions
You are using OmniCC Version (9.0.10)
Dump: value=GetBuildInfo()
[1]="2.5.1",
[2]="38921",
[3]="Jun 4 2021",
[4]=20501

What other addons are you running?
Lots ... are there any particular ones that clash ?

Have you adjusted the minimum size slider? Do you see cooldown spirals on the buffs/debuffs normally?

Sliders are still set as default "Resize cooldown text to fit within frames"

OmniCC shows cooldowns for abilities on bar and things like polymorph / banish countdowns on mobs formally.

Being that this is classic, I don’t think we’re yet in an era where buffs/debuts normally present this information

So adding "FocusFrame" to patterns for "Unit Nameplates" is not supported ? Seemed like the page in the settimgs was saying that I could add any frame name I liked. But if it's not supported (?) then fine.

"Being that this is classic, I don’t think we’re yet in an era where buffs/debuts normally present this information"

It is displated on the unit frame

PS thanks for the amazingly prompt reply

For OmniCC to display text, you need to be able to see a cooldown spiral on the buff/debuff. You might need something like ClassicAuraDurations for the focus frame https://www.curseforge.com/wow/addons/classicauradurations

I will try that .. thank you.
