MacOS and Gnome are exploring and implementing new usability features -- for disruptive cats!
example at: http://www.maniacworld.com/cat-vs-imac.html
Now, don't get me wrong. I love cats. However, I get mad when the cat walks across the keyboard. I actually don't get mad at the cat. (I do train my cats to not walk across the keyboard), I get mad at the idiot who approved of the broken UI standards
Here are some examples of problems
And some solutions

I intend to link this site to other usability and accessability research and advocasy sites, and list pressing problems and their workarrounds and solutions. --Aaron Peterson 206 334 5925
