Primarily with the aim of polishing World of Tanks Blitz for iOS and Android out, I'd love to hear your feedback on small but really nasty things, that substantially worsen your experience in WoT on PC.

This can be anything starting with battle/hangar interface to particular (though relatively small) gameplay features. Please, just don't go global with your feedback like "damage/visibility system, matchmaking, etc" - that's a topic for a separate discussion and is mostly in the interest of PC version.
