Update: Unfortunate event, my phone is broken (my pc is too slow for an android emulator) so I can't update the device preview anymore. The changes will be reverted soon:tm:.

But, If anyone is interested in updating the preview, I'm willing to try and reintroduce grid adjustment to Lawnchair 15 (as I already have it implemented but the icon doesn't scale well on adjustment)

if interested to what happened to the phone, I separated the screen from the device! How amazing! Comes with tons of cracks! Lastly, I broke the display connector!

@validcube does the preview have to be exactly like the one already present? it feels off because icon packs don't apply.

The preview will most likely match the one from LC14 (see https://github.com/LawnchairLauncher/lawnchair), the configuration doesn't have to be the exact same, the frame is aspirational.
