this is a tiny thing.... but I'd like the ability to combine folders i was just sorting through my favorites and realized I had way too many folders, I had to click on every picture to transfer it to another. It'd be nice if there was a button to just combine folders.
A way to blacklist certain tags and types of mature content, like all the 'artistic nudity' and fetish pieces that're all over the front page. I'd like to be able to go to the front page without it looking like a cross between a legitimate porn site and r34 chan.
Being able to search favorites. I am a terrible and dash type of deviantArt user. So that means I have a large collection of favorites over the years and would like to be able to clean up that collection and find individual works easier.
I.P. Ban just in case you get a internet bully who won't take a hint.
Free webcam feature. I get they need a premium account to help pay the bills but I remember when the webcam was just there.
Mutual block on shout boxes. I've experienced multiple times where banned or blocked individuals can still comment on my shout box. While it is hilarious to see them throw a temper tantrum and soil themselves, it does get old fast.
Being able to IP block someone from a user's page to deter jerks who make an account to pester the page owner with a copied reply to every comment on it REPEATEDLY, so that any new accounts from the bully have to be accessed from a new computer, probably even a new internet network.
Being able to search by multiple tags at once. Like being able to search for "series" and "character" and only get results tagged with both also on that vein being able to search for things that are tagged X but not Y. like, as a totally random example, you could search for things that are tagged "mlp" and have it only show results that are NOT tagged as... certain other things...
I wish there was a way to upload music files. I have a music making software that allows me to compose my own music and I wish I could upload them here to show my friends. But alas DA doesn't allow music to be uploaded
Tag blacklists. Some works on this sites can very well trigger gag reflex, and usually either made in Poser or have to do something with "obese" or "inflated" fetishes. I would sell my kidney to have ability to hide these works from my sight when I search for something!
