This site design is outdated

There are a number of issues with how this site functions. Lemme list the ones I can think of right now:

-no ability to undo an upvote or downvote
-changing avatar is not the same as changing profile pic, and hard to find
-somewhat dated/not sleek aesthetic
-why do we even have "add as friend" and what does it do?
-no option to post in a thread without bumping it to the top
-cannot send pictures in dm
-searching for a thread you commented in that got buried is cumbersome and not intuitive
-searching for thread algorithm does not always bring up the threads with most similar titles first
-searching for thread algorithm does not have filters i.e. newest first etc

If you can think of any more post them below.
