I find the desktop version to be flawless.

Tabs, drop-down menu, member.php, design, more - well done.. 
When plugins are added i'll make sure to test them.

Something for the mobile; if you look here. There's a bit of space on the sides, maybe try to make it less empty space on the sides?
Not sure if it was done on purpose for good reasons or just hasn't been altered. 

Good luck. HF will definitely be the first large forum to have a PROPER mobile friendly theme.

Great post Maxim. Thanks.

Mobile tests v2 (There's so many pages. Bare with me if it gets messy.)

What works

Buddy list, Profile page, Personal Notepad, Reputation page (2), User CP Menu, Board Statistics, Forum Team, Empty private messages, Change Password, Saved Drafts, Index, Report Profile, Add Reputation, Browse Forum, 

What needs altering

New UCP Menu, Compose private message, Edit Signature, PM Space Used, Forum Settings, Change Avatar, Edit Buddy List, New Thread, Search, Member List,
