Love the new owner name filter. However, it seems that you have a problem with the "&" sign. I tried it at home to filter our our famous cachers "Bo & Elisabeth" (I have nothing against them :) it's just that they have a lot of caches out so it was an easy choice to see how it worked.
Now, since I didn't know that you had the excellent auto-complete function, I pasted their name from geocaching.com and that didn't work. But if I use the auto-complete function it fills in "Bo Elisabeth" instead. So it works, it just looks weird.
BTW, THANK YOU for a great service!
