A system similar to what Steam has: Trading Cards that can be unlocked by engaging with the streamer. (Requires the streamer to have such feature enabled; The streamer can design and upload their cards and set conditions such as drop rate, how to get them, say by following, subscribing, donating etc.)

Each user would have their own trading card menu in their personal dashboard, to check which have been unlocked, from which streamers, etc.
Viewers can also trade cards with others if they have doubles, etc.
Collecting all cards from a streamer could also unlock a badge or whatever the streamer decides the compensation is (say access to all channel emotes without the need to subscribe, for example).

Please consider.

1. Go to your channel.
2. Click "Edit Panels". You should see this: https://i.gyazo.com/7431ffc77efa263da1b8753ac81f3328.png
3. Click "Activate" on one of the default extensions. A popup will appear.
4. Click "Activate" on the bottom right of the popup. The popup will disappear.
5. Click "Configure" on the newly added panel extension. A popup will appear.
6. Click "Activate" on the bottom right of the popup. Nothing happens.

When you have 3 or more activated extensions, clicking "Activate" on step #6 will display a dropdown. Until then, it does nothing.

This confuses users and causes them to send bug reports to the extension developer, when really this is a twitch.tv bug.

Whether you stream on PC, console, or mobile platforms there is only 2 components, 1 overlay, and 3 panels. I understand that this was probably the most anyone wanted to attempt when you guys 1st started. However, now you are probably the top kid in the streaming game, and this feature could use an update in amount of available slots. If these were always showing then I could see the need for a limit, but most only become visible once hovered over or located in the panel section below. So with this being said you could add more slots for us to use because I just signed up for Overlay expert and I would love to see my overlay in action on all my games I play. But, sadly this can't happen because I use extensions like the D2 official that go active the moment I fired up the game, and pushes the overlay into the inactive state. If these are overlays, shouldn't they be active whenever WE need them to be, and not at the whim of one of our auto-active overlays? I am a new streamer, by that I mean I have been streaming a long time but now I am so close to affiliate that I would love to use features that will give me an edge in regards to this milestone (as well as others). I am a studying game designer, so I know a thing or 2 about coding, and I think this is very achievable since most of the extensions are hidden until selected. Why hasn't this been addressed already? I think you would have jumped at the chance to improve this feature for your streamers since this is what this service is for, right? If not, then is there a reason why this can't happen, or hasn't happened already?

Provide a way to automate each step of the "Extension Life Cycle". https://dev.twitch.tv/docs/extensions/life-cycle

Extension developers manage their extensions through email, and a website. There's a ton of links to click, lots of waiting, never ending confirmation dialogs.. and more clicking.

I want to perform one action (one click, one cli command, etc) to move to the next, or previous step. It would save us devs a lot of time and energy.

Personally, I would love to be able to do this on the command line.

$ twitch --to-hosted-test -y -f twitch.config.js

Boom and done. Now you made a mistake and need to go back.

$ twitch --back
$ twitch --to-review ./dist.zip
$ twitch create hello-world
// ^ Think vue-cli, create-react-app.

You get the idea.

EDIT: I just realized the developer rig exists. That would be a great place to add this functionality.

It would be cool to have a option to add a client reference id when creating the transaction. This would allow me to link a transaction (before create the transaction flow) to a specific item by just using the method useBits() and the new webhook.

Currently I still have to use the onTransactionComplete. To link the item to the transaction. However, if the developer’s EBS experiences an outage, it is difficult to retroactively fulfill the benefits to viewers who have already spent Bits.

I have in an extension virtually "infinite" items which can be purchased with bits that shares the same sku. In order to assign a transaction and its SKU with an item it would be great to add a client reference when creating the transaction.

e.g:

twitch.ext.bits.useBits('virtual-item', {
clientreferenceid: 'virtual-item-id'
});

This would allow me to check the requested item with the SKU via the webhook.
