It would be nice to see how much it costs to upgrade an item already being updated so we can know how much loot we need in advance of it finishing to upgrade it again. It's also kind of a pain to be able to see the other clans bases during war to see if they have troops trained or not. You have to click on the clan castle one by one to view each opponent.
In the link below you can see any upgrade cost, time etc. adding such function in game would be redundant in my opinion.

You could always check the wiki for the first part. http://clashofclans.wikia.com/wiki/Clash_of_Clans_Wiki As for the second, although I agree, this is such a nonissue I dont see supercell making any changes to make it more convenient.
