Thumb-Key

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!

For some background, I'm a huge fan of alternative keyboards and layouts, I've been using florisboard since it got the nalmy layout and swipe typing, and switched to thumbkey shortly after it came out.

I recently have been purging my phone of unused apps and even though I always use thumbkey, I ran out of low hanging fruit and decided to compare my wpm with thumbkey and the default qwerty grapheneos keyboard. Turns out, both are ~40-44 wpm, which is definitely good (the average is 30), but given that I've used thumbkey so long I was a bit surprised it was the same speed as a keyboard layout I've only used a handful of times in years (I don't use qwerty on desktop either).

I just realized I haven't tested one hand mode, so I'll edit the post with those results, but it got me curious to see what other peoples speeds are with thumbkey vs qwerty. If you share, it would be also interesting to know how long you've been using thumbkey

edit: one handed is where thumbkey really shines. Not only was it a lot more comfortable and smooth, it also hit 38 wpm, whereas qwerty was 27. Looks like thumbkey is here to stay on my phone, thanks for the great keyboard!

The drag-and-return feature is great (unfortunately the circular drag doesn't work at all in my phone). Am I missing something, but ... how do I capitalize a letter in the middle of a key with just the drag-and-return feature?

If I type a space followed by a quotation mark, the quotation mark replaces the space, making it difficult to type start quotes. And if I try to place an end quote directly after another letter, it will either modify the letter if it's a vowel to become an umlaut, or it won't type the quotation mark unless I first enter a space. If I disable spacebar multi-taps, then I can get around the issue by entering two spaces before a start quote and one space before an end quote, but with spacebar multi-taps on, the only way to enter a start quote is by pressing space, entering a quote, going back, and entering another space character before the quotation mark.
