However, it's time for me to actually say 'well done, LJ' and 'yes, I really do like this change'.
A while ago (July) they changed the Manage Tags page. At the time of posting about this change I commented that I hadn't had a chance to use it yet, so didn't know if it was an improvement or not. I rather feared, given that all the tags no longer appeared on the same page, that I would not find it an improvement.
However, after using it for just over two months I have to say I love it. It's a huge improvement (for me at least). I love being able to search for a tag or sort by the most frequently used tags or alphabetically and the fact that if a tag exists it tells you. It has certainly made life easier when it comms to the various fanfic challenge comms I own, when assigning tags. I'm a huge fan.
So well done, LJ. Finally a change that really is, for this user, an improvement. Kudos to you.
