Script/add-on the shows final resolution

I wasn’t sure which forum to post this, but it’s related to the UI so I took a stab.

I saw someone had an addon that showed the final resolution right in the dimensions dropdown here:
But for the life of me, I don’t remember where I saw it and my google search came up empty.
Anyone familiar with it? I realize, now, that I would make use of that more often than I thought.

in 2.9 you have to go to another panel on the right
use the output panel and it will be there

happy bl

That Is the output panel.

The addon I saw showed text under there to show the actual render size. I think it may have also shown the actual render region size as well, which is also nice.

So in my first example, I had 400%. So the actual render resolution will not be 1920x1080, but it will be (19204) x (10804) or 7680x4320
I’m looking to see the 7680x4320, that’s all. I know How to do the math, that’s just more convenient.
