Ok...... where do I start....
First off, very interesting.
Now the issues..
* I was wondering where "multi-quote" went, but I think you covered it above where you said you could click the reply button on each post and it'll quote each one; problem with that is though, once you click reply on one post it will take you all the way to the bottom of the thread where the quick reply box is and then if you want to continue reading the thread before replying you have to scroll all the way back up again. Very annoying!
* Not sure there's anything we can do about this - i'll look into it*
* Was wondering where feedback was, but you covered that already
* Wanted to collapse the side-menu on the home page, but you covered that too.... not a huge deal that you can't I spose.
*Yep that's there to stay. Can't move it*
* Can we increase the size of the avatars at all!? They are rather small TBH.
*They are small and I will look into increasing them. It's on the to-do list*
* When you have a "conversation/PM" is it possible to make it so it doesn't drop down that preview box thing - I didn't care to see it and just wanted to through to my inbox, but that dropped down when I hovered over it and then when I clicked it it didn't work, had to click it again to get it to work.
*if you click straight away it should take you to the inbox, regardless of if it drops down*
As for the new PM/conversation flow..... the idea sounds good, but will take a bit getting used to for sure.
It's not VB
