A lot of those shouldn't even be voted for and it's not a matter of "want". Discussions should just have them because they are needed. Wikia should win a trophy made out of melted medals for taking the longest time for any website to add basic features. Maybe I'll get my great grandchildren to make them one after they release the features in the future. A lot of people were making petitions against Discussions back in 2016 and Fandom has barely proven to them that it's worth it. Maybe we need 2 years more for it to be acceptable.
I guess wikitext and moderation tools are novelty features. Who needs functionality and moderation, just add polling, meme upload, and emojis first. Plus change the website's name, font, and color a few dozen times. Pimp it up just a few more times and maybe Snoop Dogg will end up voluntarily wearing a pendant of the website logo. As long as it looks fun, people will take it —Fandom logic.
They all seem like good features to have, but the highlight/pin feature is what I would really like. Also I would not get my hopes up on Discussions supporting Wikitext because Discussions isn't exactly built on MediaWiki...
Most of these suggestions I would like to be implemented eventually. Wikitext should definitely be added soon. Official pins and stickies would be a good addition too. My current workaround is making a category for "stickies". One suggestion I'd like to add is the Discussions equivalent of Mediawiki:Emoticons.
