I use 5x5 grid on home screen and find a lot of vertical blank space.
I know it's low priority as not security related.
Just wondering how hard it would be to add, say, 5x6 or 5x7 option?

I used 6x9 on the previous device of similar size, 5x5 is too little for me.

dlb I already use an alternative launcher, OpenLauncher to be specific, but I'd prefer to use stock one if possible.

I'd also love to make better use of the vertical space of the home screen. Compared to Nova-launcher (which I have used for a couple of years on my previous phones), having more grid options (esp. vertical) is the only thing that I truly miss in the stock launcher so far - except that, it does a very good job!

Maybe it's too difficult for the programmers to program/add a 5x6 or 5x7 grid? Or maybe simply almost nobody missed it yet?

This is me. I haven't found anything I like as much as Nova. I do a blank home screen to keep things clean and just use the app drawer which is perfect in Nova with the tab feature. Then i have Panels running on the right side for my most frequent apps. I hate using a phone so when I do it needs to be ocnvenient as possible.
