I do.perhaps, but I don't think ED wants more than one meta label per key. (see OP.) otherwise he would have chosen a different layout (we had a few at the time with your qualifications). we might even lose another key to a second keyboard shift.
we are spinning our wheels quite a bit, perhaps over nothing. i agree though, that the latest _wb_ lacks some Je ne sais quoi. (he seems to be breaking his own principles.) i like http://www.keyboard-layout-editor.com/#/layouts/fb9f7d7dbe0e66f38f70fd7a01896878though.
it's iterative refinement, sometimes you make a good step, sometimes you make a bad one. i like _wb_'s idea of putting /? together and \| together, though, since those are companions on the US keyboard. Inspired by that, does anybody prefer:

over:

?
I think it's OK to put / together with | and \ too, to make a pattern like \ | / or / | \. The latter even looks a bit like an Atari logo
We all have the problem that there are too many keys that 'belong' in the top-right corner (according to US-QWERTY), and there's no room for them all: -_=+[]\{}| is just too much. That's why I think it makes sense to make an exception for [ ] \ { } | w.r.t. the general principle that keys should be close to their US-QWERTY position (a principle that is violated anyway by , . '), and move them over to the left in a nice pattern. In particular I like it that both ./ and ~/ are easy combos in my most recent proposal.
Another rationale behind my most recent proposal is that the keys in the center are a bit harder to reach and develop muscle memory for than the keys near the edges. So by using the middle area for "international stuff", I hope to optimize the overall efficiency.
