Whats also currently missing is Board Themed Spoilers. Basically when you go and spoiler an image, instead of being a generic spoiler like it is currently, It'll be unique the the boards theme and culture.
Second, Ban images/404
We at least have five ban images and 4? 404 error images.
Third, (if everyone wishes, a thread could be made for this idea alone) Board Themed CSS
An example of what i am talking about is old 8chan, boards like /desu/ and /fringe/ had special themes that made the board stand out and gave it a sense of culture. The main rule of that project is
1: Has to be unique to 22chan, i.e no copy pasting css scripts from old 8chan.
2: Has to make sense, be of x boards culture/match the userbase and site theme as a whole.
So currently twoot made the temple OS theme on /t/, If you feel like it doesn't properly express /t/ feel free to make a new them that fit's the people who use that board. A /natsoc/ theme on /pol/ wouldn't make much sense for our /pol/, The reason our /pol/ is currently the way it is, an anon came in around august of last year and made a good chunk of threads and left. Old /pol/ for the most part was not used much, and focused on topics of current events, it's funny because during that time it was discussed on /sg/ for "being too nice". If you had to brainstorm an example of a theme that might make sense would be perhaps CSS that makes it look like a newspaper? Times new roman font, yellow-ish background. That's an example of what could be a fitting theme based on who the userbase of that board is and who we are as a culture. Perhaps the niniba theme can be locked on to /b/? something windows XP-teir or linux-y for /t/? Something moody and emotional for /yu/? The options of creative potential are endless and i know that this project is a bit daunting, and only for the exceptional autist.
Forth and final, Image Not Found, same idea expressed above where it's diffrent per board. Currently, we have 0.
