The new tags system is amazing, makes a lot of things much easier. 

Here is another aesthetically troubling issue, on the subscriptions screen, the unsub button is very disturbing. If it could be made so that it appears once hovered over it would be better. First off it is red (which is the strongest color in wavelength to the eyes bla blah scientific stuff) and if you have lots of threads subbed to the amount of redness in there just distracts the eyes. (Or is it just me?)
