Feature request: ability to choose dimensions of home screen icon grid

When using taskbar as launcher replacement, it allows to add app icons to the home screen. As I understand, currently size of the grid for icons is determined from dpi, and in some cases it's not enough (on my phone the home screen grid is 3x4, but it could easily fit more icons, like 5x6), so it would be a useful feature to be able to manually select grid dimensions for the home screen.
