Don't limit label length (or significantly increase it).

I use the label to store the URI of the location where the mask is utilized. This can include the path to get there, the myriad arguments necessary to invoke the correct section of the page, and a text fragment of the relevant heading if an anchor is unavailable. That's about a hundred characters of text.

AnonAddy allows me to store these.
