Support macOS Window Tiling Shortcuts
macOS 15 introduced native window tiling support which previously has not been possible without a third-party app.
Unfortunately it seems that many third party apps do not support this added feature. I am seeing it most commonly in apps built with Electron.
Below are the shortcuts that I know of that should be supported. I have also linked a website that covers this a little more thoroughly.
Fn-Control-F: Fill the screen with the current window
Fn-Control-C: Center the current window
Fn-Control-Left Arrow: Snap the current window to the left
Fn-Control-Right Arrow: Snap the current window to the right
Fn-Control-Up Arrow: Snap the current window to the top
Fn-Control-Down Arrow: Snap the current window to the bottom
Fn-Control-R: Revert the window to its original size

On macOS (at least Tahoe), native keyboard shortcuts for window tiling are supported by most applications. For example, when a user hits `Fn + Control + ← (Left Arrow)` on the keyboard, the current window is positioned at the left edge of the screen. Another way to have the same positioning, is to drag the window (using a mouse or trackpad) towards the left edge of the screen. Whereas the latter works with the native Proton Mail app (not Browser), the former does not.
Please make sure that the keyboard shortcuts for window tiling are supported for the native Proton Mail app.
