Here you can see an actual difference

Tridactyl is the best. It is supporting editing textarea with vim/emacs

I'm using my corne almost a year, but still at 30-35 wpm. But english is not a my native lang. I guess I just need more time

That's a good idea

Yes, I have Arch Linux in all my laptops and all of them has the same issue after boot. I'm not using sleep at all

I have slighty different problem. Every time I turn my laptop on my Corne keyboard is not recognized, until I plug-out and plug-in again. I have no idea, how to fix it. My setup is here

Vim sucks, Emacs is the best editor in the world

It's much easier as you imagine. It always one key and in any layout it works the same. If I need to switch to nums layout I always tap twice. If I hold I switch to chars layout. This is much more intuitive than any key combination

I use tapdance to access 4 layouts.

I buy corne and at the same time I switch from query to colemak-hd and learn blind typing as well. First several days it was slow as hell. But I didn't rush myself. I tried to type with 100% accuracy so my brain is sure where every letter is placed. Humps are very helpful for this. I glue small wood pieces(from toothpick) to the key caps and my brain learn where to move my fingers for every letter. Accuracy is very important for this.

I recommend to try corne v3. It's a super popular keyboard with huge community, tons of cases and cheap to build. I'm currently using it.
