On the WebDX CG, we're trying something new to capture signals from y'all on features you need but aren't supported in all browsers.
When you visit caniuse.com, webstatus.dev, or the web features explorer, you might see a 👍 icon.
Need that feature? Click the icon to signal your interest!

Creating a universal app store for PWAs seems like an obvious win here vs. heuristics triggered installs. But think about smaller, more bespoke app stores! An app store for your intranet apps. An app store for your webring of online mutuals. An app store for kid-friendly apps. That's fun territory.
On the Edge team, we think web apps should be easier to install.
The default browser install button is great, but we'd like something which you can use on your own site, how and when you want it.
That's why we're proposing the Web Install API, which you can now test!

We're happy to announce that the Web Install API is now ready for testing on your own site, as an origin trial in Microsoft E

color-mix() has now been supported in all major browsers for more than 2 years.
It's a really useful way to create a bunch of colors from just one color.
Now is time to take a look and use it in your projects!

Temporal you ask? In all browsers you ask?
Well, I'm told it's coming to Chrome/Edge 144. So, like, very very soon (as in, January).
It's already in Firefox. And being implemented in Safari too.

Yesterday at TPAC I publicized my draft proposal for adding a declarative templating API to the DOM.

The repo has:
📖 Explainers for the templating API and DOM scheduler API
🏗️ Full prototype implementations
⚗️ a JSX transform
⚛️ a mini React-like framework

So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.
