Re: Focus indication on press on mobile

It's an interesting request, and I can see that could be useful for many
people with various vision impairments. It's similar to links taking an
active state when pressed (though that still relies on the developer adding
CSS for it, and is only seen if the new page takes a while to load).

If the button does something obvious like showing a drop down panel, then
it wouldn't be necessary. But often changes take place out of sight below
the fold, or aren't obvious for various other reasons. Like pressing a
search submit button and results are listed below the fold.

Would other people with vision impairments like to comment about this idea?

If so a suggestion for adding it as a recommended best practice in W3C
documentation could be suggested. I'm not sure it could be made a WCAG
requirement as you wouldn't want it on all buttons all over the web. But
there again it might be possible to come up with some formula to require it
when the result of pressing a button is likely not to be obvious.
