Max icon for when a structure is upgraded as far as possible with current TH level

When you click on a structure and it tells you the current level it is at, there should be an additional icon that pops up when it has reached its max-upgrade for the current TH level. Maybe something like a red x next to the level when you tap on it. It would be so nice to be able to just tap each structure and quickly see what you can still upgrade instead of having to tap it, hit upgrade and then find out you can't and then have to exit that screen.

Thank you for your consideration!!

Yeah, that makes sense. I've seen a similar request by someone for troop and spell levels. It's not always easy to see or remember what's a max level for a particular townhall level.

I'd like this feature a lot, more quality of life improvements hehe, especially on my troops as of late, I forget which can be done and which are needed to upgrade, although I can just go to the lab, it would make things easier. Same for buildings, making sure everything is done, I think adding a little screen to the Builder's icon, or expanding the current to show everything that's been done would help a lot.
