I don't know when the Up Arrow widget that rockets you to the top of the thread appeared but I really like it.
 
Also a Search generates a pop up window on the right of my screen.  That one is very nice, as well.
 
Thanks for any improvements that you do to the forum.
 
EDIT:  Might have spoken too soon about the pop up Search results window.  This isn't appearing in Firefox on my office computer.
 

That up arrow is for touch but it works with a mouse too.

I had no idea what that floating arrow was for..  nice find!
 

I can "touch" with my mouse :)

Oh, the comments one could comment...  
 

Oh yes "reach out and touch something". 

BTW, I finally figured out that the search result window flies out if you do a search (on the black bar) of the entire forum and not a sub forum.
