I love watching some streamers, but sometimes the music they play is a bit too loud or quiet for my personal taste. It would really be great if there was some way that I could adjust the volume output of the music on my end to something that is more enjoyable for me, and allows for everyone to have the music at the level they want

To optimize the SEO, I recommend that the name of the extension should be included in the title of the extension detail page.

Currently i'm getting search result like:

Extensions - Twitch
https://www.twitch.tv › ext
<description of the extension> ...

I am of the opinion that this would significantly improve the visibility of the extensions and make it easier for streamers to find the extension when searching via search engine pages.

With the announcement of the mod view at Twitchcon 2019, it would be great to have moderator views for extensions.

A moderator view would be optional and would allow moderators to have some control over the extensions (equivalent or less than the dashboard view)

Some extensions, do use image upload.
To avoid flaws in the moderation system it would be great to have an image upload system on Twitch.

The streamer or developer could upload an image, that will be reviewed by Twitch, like emotes or cheermotes, etc. Once the image is approved, it can be used in the extension on the streamer's channel.

This will allow streamer to have more personnalisation options in extension, without adding multiple image upload system for each extensions that doesn't go through the twitch moderation system.

Today extensions (overlay extensions) are only available on certain web browsers (for PC/MAC).
Make it available/work on all browsers.

Today extensions (overlays) don´t work on mobile and tablets (apps).
Make it available/work on mobile and tablet apps.

Please also find a way to make extensions synced, be able to be used in replays/VOD´s/Clips.

The title explains itself.

Explicitly state somewhere in Content Policy (https://dev.twitch.tv/docs/extensions/guidelines-and-policies/#4-content-policy) that integrations with certain products competitive to Twitch may be rejected on review.

Currently viewers can make an extension invisible via the extension taskbar but this setting does not persist. There are some channel extensions that I find useful and others that I find to be intrusive.

My only option to remove intrusive extensions presently is to disable them all (by automatically removing the extension-content and extension-taskbar divs). It is a shame to have to disable the functionality entirely for the sake of a few irritations.

It would be awesome to be able to directly link to panel extensions below the video using an anchor tag.

Allow an extension to be seen/used only by the streamer, as well as their editors and mods.

I personally still don't know how to enable extensions on my mobile device, nor do i know if its an option. I would love to be able to use extensions/overlays, or use buttons in general on my mobile device or if im streaming and i have viewers on mobile.

It would be nice to be allowed more than 1 overlay extension and 3 extensions total.

Having something like a schedule / StreamLegends takes up two, but with more of these being added, some of my viewers would enjoy having other things to do on the channel page as well as they like the Twitch Games.

IE: The Powered Up Bits Animation overlay would be nice to have for viewers to add a little flair to their donation, but some still like to play the scratcher, mini-game, etc. This requires those of that use that overlay to sacrifice it.

It would be nice if we could filter the available and installed extensions based on criteria like overlay/panel, info/widget/game, or related stream content.
