It’s common knowledge that Apple and Microsoft have consistently copied ideas from each other, dating back to the early days. What’s absolutely crazy is that macOS never properly copied window management that was introduced in Windows 7. At the very least, it’s puzzling that Apple never built in the ability to use keyboard shortcuts to snap windows to the left or right half of the screen.
That problem has obviously been solved by a plethora of third party apps that utilize the Accessibility APIs provided by Apple. There’s actually a ton of these apps, and many can do all sorts of cool window management tricks. When there’s over 20 apps that all have this functionality, and one of them has been the top paid app in the Mac App Store for years, I think it’s quite obvious that some better window management functionality should be built into macOS by Apple. The current split screen functionality for windows in macOS is pretty nice, but it’s just so much easier to snap windows with a keyboard shortcut or by dragging a window to the edge of a screen.
Taking these ideas one step further, I’ve always been a fan of managing my windows with macOS gestures. I had actually written the Multitouch app with this idea in mind. Up till now, I have always wired up the Multitouch app’s keyboard shortcut actions to a third party app’s keyboard shortcuts for snapping windows. It’s worked well, but it’s a little painful getting it all set up. As of Multitouch v1.14, I’ve built the window management functionality into Multitouch itself, so there is no need for another third party app to perform these actions with the trackpad or Magic Mouse.
Porting Objective C to Swift is a topic worthy of another post, but from all of this I created an app called Rectangle. Give it a try!
Back to the main reason for all of this: adding the functionality into Multitouch. The real benefit to having this built into Multitouch over just mapping keyboard shortcuts to another window management app is that you can now perform a window management action on the window that the cursor is over, not necessarily the frontmost window. This behavior isn’t enabled by default — you’ll have to go to the preferences and check the box for “Snap window under cursor”. I’m tempted to make this enabled by default, though, because it just feels really smooth and intuitive. Try it out and let me know what you think.
