I'm really trying to find a southpaw keyboard with the perfect layout as well. I've ordered both the EPOMAKER and Mountain Everest boards (both of which yet to arrive / use)

If you're an excel poweruser, you might find a common key combo is the CTRL + <directional> and CTRL + HOME/END keys to be used quite often. For that reason, I feel like doing away with HOME/END keys it is probably quite detrimental.

The other thing is if the arrow keys are on the right, then you probably end up having your hand off the mouse anyway, which kinds of defeats the purpose of shifting numpad to the left in the first place.

I like the delete key on the top right, that's kinda interesting.

Perhaps this layout is ideal? What do you think?

Ahhh I wish I knew this a few weeks before. I bought the EPOMAKER one but I dont think I will dig the layout (I haven't collected it yet)
