I've added jQuery and the terrific tablesorter to PBooks, so at least the ledger is now more user-friendly. On javascript enabled browsers, users can page through the transaction records much faster, as well as sort the rows by the column headers.
I hope to add more user interface enhancements like this soon, including "flot", a charting and graphing system written in javascript and also uses jQuery. As always, feel free to let us know if there are any additional features added to PBooks.
