First, let me apologize for the replay UI bugs. I did most of the work on that and did my best to try and track down every little bug, but apparentlky I missed some. I stayed late tonight to make sure to get those fixes in for 1.2, and I am pretty sure I got them all.
The minimap issue is a little different because that requires someone to create new textures for the minimap, so that may or may not happen. I have a request in, so we will see what happens.
Zechnophobe: Shop and citidel screens will pop-up if the person you are viewing (including AI) visits a shop while you are watching them.
Alterschism: Health and Mana bar text (the numbers) is not supposed to be viewable unless you hover over it. If I am not understanding you correctly, please let me know.
The minion item stacking issue is my next project (there are a few of them). The problem is it will have to go through a balance check first. It should not be a problem, but you never know. If it doesn;t make it into 1.2 rest assured we know about it and are working on fixing it.
