Ugh I post too slow, your post wasn't there when I posted. >_>'
Anyway, it's a nice idea. Though on the other side, not much will go to the member list, even if it's for going to their profile. Most people (like me) go either look for a post in the thread (which is easy to find active users on the last pages), or go use the search member from PC.
But if you think about it, it's nice and faster.
