Why is Steam (Windows PC version) the only program (to my knowledge) that natively snaps to windows displays?
Try it. Move your Steam window around. See how it snaps to the edges of your display(s)?
Why is Steam the only program (I know) that does that natively? I would love for ALL my Windows programs to do that (without installing 3rd party softwares/scripting).
All my windows snap like that, I don't know what you're talking about. Just go to System Settings, search for snap, go to Window Behavior, click on Movement tab at the top. You can configure your window snapping preferences here.
That doesn't really help in my experience because this state is not saved. You have to do tricks in order to get it saved like move the window a bit or resize it etc.
IIRC, Windows key and Up arrow will maximize it. Not aware of a way to snap a window to the top without it changing size. Would be pretty cool.
You might want to check out Windows PowerToys and specifically Fancy Zones. You can create your own areas to snap windows into. Still not quite what you're looking for but might provide an alternative approach.
On windows 11 I'm having a hard time finding apps that it doesn't work with. Firefox, paint.net, inkscape, audacity.. all work. And every single application made by microsoft also works
Steam did this back on WinXP in the early 2000's as well. To be clear, OP isn't talking about dragging a window to the very left side of the screen and it snapping in place covering half the screen. They're referring to any sized window retaining its aspect ratio but snapping to the exact edge of any side of the screen or taskbar.
No. I know the Windows snapping to edge, which resizes the window to half screen. That's not what I'm talking about here.
All I want is any program window moved to neatly align with my screen edge and with other wondows without changing size, instead of me having to align them pixel-perfect.
Don't worry friend. I know exactly what you're referring to and I wish it was more common as well. I hate having to use that bit of brain power to appease my OCD and have the window be perfectly aligned to whatever edge I push it up against.
There's an old program called allSnap that would do this to almost every application, dunno if it still works on newer versions of Windows or not though...
