I’m sorry, my script is merely client-side. That weird animated way of loading posts one-by-one into the editor (Tumblr dev funny), is not just for fun, that’s actually how it functions, with interval server-pounding httpxml requests (Tumblr dev funny). So the select-by-tag, and show-only-by-tag actually need to make a call to the open database that returns the tags for each post as they load one by one (in order to know the tags).
My only solution for you (as Tumblr wrote it, and as I wrote the third party sidekick) is to let all your posts load first, then start selecting.
I added a visual cue, that CSS-style box shadow, which means those certain posts have become applicable for my bonus extra features.
Turkey Quesadilla Romaine Pizza
(for when I accidentally buy lawn romaine instead of iceburg!)
Did I just buy bread bananas? What will this taste like?
A video tribute to the art style of my new unfollower. I still follow you, so I will still see your stuff every now and then. I like your stuff anyway.
