i saw recently that there is a first algorithmically optimized layout added, RSINOA. i’m wondering:

• is it actually good?
• is anyone using it?
• how much better is it than normal thumb-key english (if it is)?
• is it worth learning it if i already know the thumb-key layout without looking at the keyboard?
• is it in it’s final state? or are big changes to the letter placement expected and i should wait before learning it?

thanks!
