It’s easy to adapt to. You can enable/disable features of XKit. It fixes replies and allows wrapped tags. You can block content. You can reblog and add tags to posts without leaving your dashboard. It gives you the classic tracked tags layout. It allows you to access and reply to mail without leaving your dashboard. And there’s so much more. It basically comes with a bunch of extensions that are useful and you can choose which ones are best for you and turn off those you don’t care for. I’m not sure how Xkit is working with the forced beta-testing of tumblr’s new possible layout but from what I’ve heard it’s still working.
