Not sure if this is the correct forum, or if I should get an account on sourceforge, or submit to the "dev" list...
I love your tool! Kudos are definitely in order.
At least one additional feature would be helpful, at least to me...
I am a silly user, and weak at sql.  I like to browse a couple large tables (10000+ rows.)
If I change the session properties to Not "limit rows", fliping between tables is evil. 
If I leave it alone, I can't see the last rows of the table.
Sorting, of course, only sorts what has been downloaded.
     An alternate way to specify the sort (before the data is fetched) would be helpful,
     or perhaps a set of buttons for "First page", "previous", "next", "last page".
     Maybe both. :-)
