Any suggestions...

Is there a Thesaurus add-on for PocketWord. If not can someone recommend a word processor with this feature built in. It's more efficient to do an immediate synonym search instead of opening a standalone Thesaurus.

Also, I'm looking for a Dictionary functional enough to let me look up a word in any program. I don't know if this is feasible, but it'd be great to be able to highlight a word in any program (PIE, Avantgo, Mazingo etc.) and pull up a definition. This is one of the best features of Microsoft Reader. Anyone know of a program that allows this across all text programs?

I've already got Lextionary. It's great but I didn't find a universal search feature or a way to link it to PocketWord (not that I expected it).

I appreciate your help.
