It would be better if LT used option dialog inside OOo rather than custom Swing ui which looks inconsistent with surrounding UI and desktop environment (at least on Linux).
From OOo website: "Extensions can add options pages to OpenOffice.org's options dialog. They should not create their own menu or menu entries for the sole purpose of configuring the extension. This is what the options dialog is for." (http://wiki.services.openoffice.org/wiki/Documentation/DevGuide/Extensions/Options_Dialog)
