The problem is the main thumb keys are long, which obstruct the other keys. This is okay for independent utility keys, but not for combination rolling with fingers, especially when speed and accuracy is involved. Big keys also affect the impact point of striking a key. It feels weird to hit a key other than at the center.
Instead, they can split the big keys into smaller keys. This should improve rolling with fingers and provides extra keys for the thumbs.
See attached for my attempt at a thumb cluster. Did not work as well as I thought it would.
It's one of the things I like about the ErgoLinear layout, but getting a single-size key (1U) that is thumb-friendly (ie convex rather than concave) seems to be impossible.
There's something about enabling cross-server scripts for local servers.
Am reluctant to rename all the layouts from standard.layoutname to layoutname.standard because then I need to also change them all in the iMacros script in Firefox that does the automated testing for me.
But I agree the standard.layoutname may have made sense in the past but now mixes up different variants of same layout.
Currently testing 182 layouts... need to remove all my 'experiments' so that it goes faster. Took over 3 days, and now the loading process is making me jump through hoops because I had slight differences in the layout files and the names I loaded into the database, and MariaDB for some reason is now doing case-sensitive searches where it never used to before...
Will post results table later.
