align the launcher grid options and icon sizes with the Pixel Launcher
This should match what the Pixel Launcher offers without extra options or different icon sizes, etc. It should be kept aligned and ported to the new OS versions in advance. We'll only merge an implementation of this feature if someone demonstrates they're going to keep it well maintained.
Pixel 9 with stock OS has 5x5, 4x5, 4x4, 3x3 and 2x2 so we're missing 4x5. May vary on other devices.
2x2 should not be available for tablets. It was missing the phone marker used for the other phone layouts. That's fixed now.
On my Pixel 9 Pro XL the top search bar in the launcher appears to breach the padding ever so slightly. I am not sure if it is related.
Please also include 4x6 and 5x6, as I find the gaps between rows to be huge. It's not as bad with the stock Pixel Launcher, because it has a search bar at the bottom, which takes up some space and reduces the vertical gap size. As GrapheneOS does not include the Google search bar, I think there should be these extra options to better match the spacing of the stock Launcher.
This is some stock photo that shows what it looks like on a 7a (I believe?)
