I just updated from 0.1.1 with your package. Nice work btw.
Did someone encouter the same problem than me, that after updating all user-specific settings are gone? No adressbook, no signatures/identities are left. All blank. Anyone else?
Edit: Nevermind I found the problem. If you go with the docs and delete the old roundcube module, you will also loose the sqlite DB included in that folder. To save settings like identities etc. copy sqlite.db to a safe location and insert it back after installing the new module. Same goes to all modification of skin or alike.
