This is already implemented via Racknet.

This is already possible.

Most or all of these have already been suggested in older, more specific posts, so you have a better chance searching and voting for them separately instead.

Some decent ideas here. Sometimes I feel torn on which way to vote for characters that I think are very well designed, but aren't to my tastes as a client.

Some other suggestions: A way to reverse any sorting parameters (i.e from least to most votes, oldest to newest)

Usernames, for those who want a middle-ground between being completely anonymous and sharing a personal email.

A stat showing how many people have favourited the character.

An arousal slider like in the character editor, since you can't tell what's inside slits/sheaths otherwise, and it might end up putting you off a character once you actually get them in your lab.

Yeah, I've noticed the same issue sometimes.

I do like the warm lighting, but there ought to be a simple button to toggle it while editing.

Not sure how it's possible to miss the odd themes here even at a glance.... but I almost hope he did, I had a good laugh when I saw this posted. xD

This seems to be already planned: https://trello.com/c/ZsFob8gt/83-develop-a-new-player-welcome-sequence

I think anything very in-depth should probably wait til later though, as if you made a detailed tutorial this early on, it'd become inaccurate whenever something is changed.
