My first gut-reaction is that it shouldn't be the place of an information display mod to handle UI elements in any way. This is compounded by the fact that nearly every minimap mod out there either hides that armoured-dude by default or provides the option to do so, so in my mind it's something that's a part of minimap mods. Are neither of you running minimap mods? I thought the use of minimap mods was common-place, if it's not then I'll consider adding in that option.
Hmm... don't know mini map mods, which can hide armored man
Attrition closer replacement of FuBar_DurabilityFu, both can show durability, auto repair, but Attriton can't hide armored man :(
Don't resize your screenshots. It's hard to get an accurate look at your UI (and give relevant feedback) when you give us a picture that's 20% actual size. From what I can see, I'd say you have quite a bit of wasted space between your unit frames (which are incredibly gigantic) and your action buttons. The right chat area is also fairly wasted, since EavesDrop is only occupying at most half of that space. Again with the wasted empty space between your raid frames and left chat area. Also, the raid frames don't seem to have any particular horizontal alignment with anything else.
Between UF and AB - Quartz(player+target)
On right side Omen(raid only)+Demon(raid\bg) + EavesDrops(always visible)
