It would be great if there could be a pop-up appear for viewers when opening a stream that shows them the details of any content warnings for the stream's selected game category.

There are an increasing number of games that contain content and/or trigger warnings for players at the start of the game, which is great. However, they are generally only displayed at the beginning of the game and not shown again after. If a viewer is exploring Twitch and opens a stream after the initial content warning has been displayed in the game they don't get to see it. Having a game content warning pop-up when opening a stream, similar to the mature content warning we get if a channel has been flagged as mature content, would help to create a safer and more accessible browsing experience for viewers.

Allowing game devs/publishers to select in the Twitch Developer Console if their game has a content warning and the giving them the ability to add their own warning text to a pop-up for viewers would likely be the best way to add this feature. Perhaps there could also be a way for viewers to flag if they feel a game requires a content warning pop-up.

Consoles we are playing should have their own tags. It would help people who enjoy certain consoles to find content they love. This can apply to current generation games and retro. Since Retro is a category that is healthy and growing with lots of talented and incredible broadcasters, it would be cool to have tags based on the system we are playing to help discoverability. Since streaming in each game tends to make the experience more fragmented, people tend to stream under the general Retro category. When streaming under retro using a tag for the system you are playing could be helpful. Example tags could be;

NES, Super Nintendo, Nintendo 64, Virtual Boy, Gamecube, Wii, Sega Master System, Sega Genesis, Sega 32X, Sega Saturn, Sega Dreamcast, GameBoy, Amiga, DOS, Atari, Commodore 64, Original Xbox, Playstation, Playstation 2, Playstation Portable, etc.

This is by no means an exhaustive list of console tags that could be made, but I wanted to at least get the idea going to see what people think. The idea would be every console should have its own tag.

In 2016 Insomniac released Ratchet & Clank for PS4 with the same name as the original Ratchet & Clank for PS2 released in 2002. In IGDB they are separate games, but because of the naming collision it seems Twitch is prioritizing the latest released game. The original Ratchet & Clank still has a decent amount of players and it's a very separate game from the reimagined PS4 game.
Is it possible to resolve this naming collision manually?

The two games are not the same, the PS4 game is a reimagining of the PS2 game with a different game engine and a different storyline. It's not a remake or an HD edition.

I'd like to stress that both games are in IGDB, but only the latest game shows up as a category on Twitch (probably due to the naming collision).

These categories are all part of the same game.

Fire Emblem Fates:
* Fire Emblem Fates: Birthright
* Fire Emblem Fates: Conquest
* Fire Emblem Fates: Special Edition

Fire Emblem Fates is currently subdivided into "Fire Emblem Fates: Birthright", "Fire Emblem Fates: Conquest", and "Fire Emblem Fates: Special Edition", which corresponds to the physical releases the game had. However, the listings and by extension, the physical releases, are more akin to routes within the same game and dividing the category just makes it harder to list and search for streams. Furthermore, the current listing doesn't even have a proper category for Revelation, the third route, as it's not covered by the "Special Edition" at all.

Fire Emblem Fates is considered by the developers and the fanbase to be Fire Emblem 14, a single entry in the series, and it would be beneficial for everyone to simply merge them under the umbrella "Fire Emblem: Fates".

However, due to a peculiarity in how the title's boxart was constructed--being a very horizontal image meant to combine into two halves of a single whole--there doesn't exist a great listing image using just the unedited boxart. The full image, when focused on the merging point and with the logo added atop it, serves well as a listing image, representing all three routes and their representative character. In the interest of having a professional looking listing for title and better legitimizing streaming the game, I'm including images that fit the dimensions used for your site listings: https://imgur.com/a/wYpb4iU

Currently the top views are in the top of the list for followed channels. In categories it is the same way. With disabilities we often can't stream the hours or consistently stream like those that do. So finding a better way to be discovered will help those with accessibility needs. We have a voice but sometimes we are not found due to current set up.

It will also make it safer for other streamers that are not disabled. As many people give out bad advice to just constantly stream such as to not work or sleep. That streaming to be found is more important than having an outside life.
