Looks like Tumblr changed some stuff again.
First, Tumblr implemented it’s own "Quick Reblog" feature, which.. well, only reblogs the post, and does not allow you to pick which blog to reblog to, add tags, add caption, queue or draft. It’s like a retro, 1980s version of XKit’s One-Click Reblog.
Secondly, Blank Posts extension is blocked again with the changes. I am working on fixing it.
And lastly, hopefully, I have some big announcements for this weekend.
Thanks for using XKit! =3
