Pin window to Top (aka Always On Top)

[luckman212]

A very useful feature to add to Loop would be "Pinning" a window to the top of the screen. While macOS does not offer a native feature to do this, some clever apps e.g. Topit have used ScreenCaptureKit to make a "clone" of a window and keep that clone on top since it's owned by the app itself. This works fairly well.

It would be a good feature. Can you writhe an issue for that?

I’ve recently been looking for a solution to pin windows on top, and I noticed in the comparison section of the README that it says Hammerspoon supports this feature.

I’d like to know the reference or source for this claim, because I couldn’t find any way to implement this feature in Hammerspoon. In fact, there is an issue requesting this functionality in Hammerspoon, but it was closed as “not planned.”

Hi, apologies about this! This table was originally created nearly a year ago, and we didn’t keep track of the original sources, but I’ve done my best to update it based on the window managers’ websites and other public sources. Thanks again for reporting it!

Thanks, and, did Loop has any plan/interest to implement the always on top feature? If yes, I'd like to create an issue.😘

You’re welcome to create an issue! The main challenge preventing us from implementing this right now is that if we use ScreenCaptureKit to stream a window into a floating window, it would prevent the original window from being interacted with. The alternative would be to manually raise a window after each focus, but that feels a hacky. That’s why it hasn’t been implemented yet.

If we ever figure out a way to either use ScreenCaptureKit while keeping it performant, or find another approach, we’d be happy to revisit and implement this feature.
