MacOS 27 shows a handle for resizing when the screen is split between two windows. Dragging it resizes both windows at the same time.
Two windows, one on the left and one on the right with their borders touching in the middle. Where they meet, there is the cursor for horizontal resizing for the left window. Underneath it, there is a short and narrow vertical rectangle that serves as a handle for resizing both windows.

CSS keeps getting better and better, but the problem with hearing about amazing new features is that we're stuck not being able to use them for a few years because of browser support. So, this week I looked at a bunch of well-supported CSS features that I still see people turn to JS for.

In a time when most companies are so openly playing against their employees and the rest of us, we should celebrate the existence of beacons like Igalia that shows them it's their choice. Organizations can definitely thrive with fairer structures and be a strong positive force for the world.

Fingers crossed! Not a fan of the shortcuts UI either. My Logitech keyboard doesn’t have Globe key, so I defined my own shortcuts for tiling left, right, etc. MacOS changed Ctrl-Opt-Cmd-▶︎ to simply Ctrl-Opt-Cmd 😬 Desktop shortcuts are built in but don’t work (anymore)—see below.

Still a lot of bugs there, it looks like: I added one shortcut and as a result, macOS messed up my old shortcuts (it changed the key).

Preact 11 will be tree-shakeable, you pay what you use of preact/compat. Soon you won't pay for createElement when using the jsx method. We're continuously trying to give the smallest bundle size, and 600 bytes saved might not seem like a lot but... to us it is
Side-by-side BundleJS comparison showing preact/compat before and after becoming tree-shakeable. The current version bundles render at 7.06 kB gzip with a 1.56 MB publish size, while the release candidate bundles the same import at 6.49 kB gzip with a 601 kB publish size.
