JohnB:
In my games there are often more than one 'current' thread at a time.
I knew someone would point that out!
In such a case you just wouldn't use the feature :)
I'm not in favour of having/moving the Game Menu link to the left, as I'm happy with where it is - that's where I know it is, to move it would be confusing. If it vanishes on some pages though (I haven't noticed) I'd be all for making it persistent.
Can't comment on the sticky list as I don't know what it's for...
