|oSoSo —> Pocket Viewer —> addinpack|
This Linux program packs several (small) Pocket Viewer addins into a single one. Thus it's possible to have more than 16 addins installed at the same time.
The first packed addin of a collection is invokable by the menu, all other addins have to be started with PV-AddIn-Manager.
Please note that addins for PV-S1600 are probably unsupported.
