Re: Running ChromeVox as a library in a web page?

Yes. I suppose there is always a way to decompose things to better fit
existing prescribed patterns. However, we all exist in a practical
context. It is not always possible to prevail upon people we are dealing
with that they need to completely redesign their UI, especially if it was
not the result of the whim of some overly creative developer, but, rather,
involved quite costly usability testing that just didn't happen to include,
in its sample of participants, screen reader users. Working in a
competitive environment where companies are always trying to distinguish
themselves by providing a more fluid experience--for some users at
least--means sometimes one needs to make what is already there work as best
it can, and encourage the building of a culture moving forward that
considers a broader set of users when making design decisions.
