Missing features in osu! chat

[vatei]

As mentioned on the osu! discord before, the osu! chat is missing some features, making it feel barebones and less legible.
Here are some of them I think are important:

• Highlight mentions (color or bold font)

  • Additional highlight when receiving a mention (maybe using a fading highlight animation)

  

  The existing notification could be used only when the chat isn't visible

• Autocomplete mentions using tab

• Block user

• Mute user (prevents notifications)

• Right click menu on messages

  • Mention (same as the existing one in the username right click menu)
  • Reply (would quote the message or part of it if it’s too long. Doesn't need to be added to the chat box, maybe with a "reply"/"replying to user" indicator and the mention, then the quote is displayed after sending a message)

  
  

  • Report message (meaning the content of the message would be appended to the report)

• Ability to change the color of the username (or matching it to the profile hue)
  Partially discussed in Standardizing colors and having better visibility for links on chat #23145 (comment)

• Accessing the daily challenge chat via #daily-challenge (useful for chatting without having the daily challenge screen open)

I included some paint mockups to explain some points, hope that makes it clearer
It's mainly QoL, so I hope some of them can be implemented, thanks again for reading!

Edit: added a few more ideas in the comments

Mention highlighting and alternating line colours have been implemented.

• Being able to do !roll in chat is also missing (it's dumb but I miss that)
• Ordering direct messages by last message ( Direct messages in chat aren't ordered by recent activity #18461 )
• Being able to collapse the "channels" or "direct messages" sections in the chat window
