We have updated our free PDF Viewer and bookmaking plugin (which allows you to view, search and also bookmark all your favourite PDF files (including ones from the Internet). It should be much faster, includes a large number of enhancements and fixes and now tells you when we release new updates.
The update is on the IDEA repository and full details are at http://www.jpedal.org/support_siIDEA.php
We have also altered the Open Source license used from GPL to LGPL.
I hope it proves useful!
