"Visual center"

[ivansavra1]

Hi! I love Rectangle, I always wanted this little feature and only now had the idea to share it, it would be perfect for my use case if it had this: The "Center" action anchors windows to the "True center" of the screen, whereas macOS centers new windows on the visible screen area (i.e. the screen minus the menu-bar at top and the Dock at bottom), which is more pleasing at least for me, and this would be easy to implement, you'd just need to anchor the window to the center of NSScreen.main!.visibleFrame rather than to the full screen bounds.

Thank you for maintaining just awesome software and keeping it open source!

Thanks for the feedback. Rectangle is using the visible screen for all of its calculations, including Center, so I suspect you might be hitting a macOS bug where the dock is not accounted for in specific situations? In the past, this might happen when the dock is unhidden or a display is connected.

@rxhanson Hey, sorry for the late reply, this is weird, I have been using Rectangle for two years now, on different macOS versions and two computers, and I don't remember ever seeing it center windows like macOS does with new ones (Apps and dialogs that have never been moved by the user), and my Dock is never hidden.

After some testing, I see that I was technically wrong with my suggestion, what I'm referring to, which is hard to point out because Apple's documentation vaguely calls it "Slightly above the center", is basically the visible screen center plus 10% or 20% of the dialog/window height, this part of the OS is not open source, so I don't have the exact number unfortunately.
If you test this, I think you'll get what I mean with this, it's frustrating that I can't get ahold of a screenshot showing the default position at the moment, sorry about that.

Got it. I think this is what you're looking for:

@rxhanson Thank you for your help! Is there a way I can assign that for snapping?

[rxhanson]

Not at the moment. I see no reason to turn down a good pull request that can do this, though.

As an aside, this is available in Rectangle Pro (paid) as "Upper Center", or can be custom-created down to the pixel distance or screen percentage from center as a custom size & position.
