For people who are trans and/or non-binary, letting streamers know your pronouns in chat so that your gendered correctly can either be awkward or difficult. An option for people to add their pronouns in brackets beside their usernames or in their profile cards in chat might help to let the streamer and/or chat know if a user feels it's important.

there is still no option to change the letter size - only by using bttv! Would be very very nice to do it directly on twitch without a 3rd party tool! Also i suggest an option for different sizes for the video/stream player - right now i have big video window which uses to much space

Current dark mode with the new twitch app on phones and black (#000000) colored names do not work well, while white (#ffffff) colored names are being changed to light grey.
Please change #000000 to dark grey. Thank you.

It would be very nice, if it's possible to delete your own message in the chat. It happens sometimes that you write something what sounds pretty good in your mind, but if you read it in the chat after sending it, you recognize that it wasn't such a cool Idea to post it or you mention by yourself that your message is stupid and want to delete it. A cool way to implement this would be, if you add a little bin between the own message, that you can easy delete it by clicking on them.

I feel like it'd be pretty simple to implement:
allow mods to toggle their chat messages to be hidden from the viewers. This would be useful in the case of chatbot maintenance (so chat isn't flooded with command lines), asking the broadcaster a sensitive question, or just allowing the mods to work behind the scenes unintrusively.

The new twitch chat is impossible to read and gives me a headache when trying.

Emotes to be used by Bots, with company logos like Twitter, Instagram, Discord, to support the transported messages.

Maybe also some other emotes (Twitch Prime, or Subways for next Subtember).

As there are some bots with regular Account names, it might be cool if a broadcaster can assign a bot role to a user, and this user can use the bot emotes.

Maybe limiting it to 3 bot users per Channel.

Maybe bot can be similar to mod role, just with the extention to use the emotes/icons.

Or: Allow all with mod-role to use this specific emote set.

In slow-moving chat the “More messages below.” text obscures the last message. Maybe it would be better if it was a bit lower down so we could read the last msg?

Faster refresh of chat on mobile. 1 second chat update time feels too slow to me for bigger streams which means it's possible to miss messages. Processing power isn't an issue as third party apps manage to do it on my phone

Hey, i'm a french user, and i want to know if my idea is possible
I want to know if it's possible to create an option for popout chat when we are on redifusion of stream, that is so interesting when someone have two (or more) screen and want see the redif in fullscreen.
It's basic and not a priority but it's interesting for some viewer, I think
Sorry, if my Englis is so bad :/
Thanks for read

When watching popular channels, the chat is often a wall of emote spam not saying anything, and any 'actual' chat messages disappear too fast to read. It would be very useful to hide any messages that are just repeated emotes.

Some people don't mind watching the chat replay. That's fine. But others do not like it. If viewers had the option to hide chat replay like they can during live streams, everyone would be happier. It would also reduce the amount of resources needed to view videos, especially for lower end computers.

There is absolutely no possible downside to adding the ability to disable chat when watching replays.

hello I am a VIP in a live and I always try to help my friend who is a streamer, but always has a person who creates several accounts for spamming, cursing and other things I would like to know if you can twitch block the ip for him never again do this in no live
thanks for your attention

I think the actual badges like Moderator or Twitch prime don't look good compared to badges like the Gift Sub badge, I suggest to redesign the squared badges, we would like material design badges that are not squared, for the moderator badge I would like to see only the sword and not the green squared.

Allow streamers to set the number of comments that are allowed to be posted in their chat channel per minute, implemented through a simple comment queue system.

Hide mod activity from users (eg. which mod banned someone).
