For some suggestions you mentioned, Fandom Open Source Library has got scripts for these that are capable to be implemented in wiki chats. ^^ You can add the ones allowed to be used site-wide on wikis, or add ones for yourself that are not allowed for site-wide use or can be used personally: Also, suggestions like this are better to be directed to Staff through Special:Contact/feedback. :)
 * ChatTags - Bold, italic, strike-through, text color, and so on. Allowed site-wide.
 * EmoticonsWindow - Emoticons list. Allowed site-wide.
 * LightBlock - Personally mute user. Not allowed site-wide.
