> I don’t think it is useful to write faster than I can ‘think’. What I like about writing is that I can hone my thoughts to be sharper than they would in everyday speech by reworking them over and over.

Sorry for an offtopic but a decent layout is not so much about speed, it is about helping to get rid of some needness to watch the keyboard. If you can not enter your password without looking at the buttons than the honing of your thoughts gets obstructed with needness to look at elsewhere except of the thoughts has been written already.

Definitely not working about choosing right layout (because of changing a layout is way harder than changing a text editor). But as another bilingual I am sure your choice works best for your languages and hands/fingers.
