Run versions 6 and 7 in parallel

For me personally, version 7 has slight advantages (conversation view, longer categories drop-down list for contacts, better telephone number handling for contacts) and many drawbacks (less agreeable design wasting screen space and missing lines, notes not on first tab in contact), and I will uninstall it in order to use version 6.

As versions 6 and 7 use different databases, it would be an idea to have them both installed, so that I can test version 7 once in a while and finally cut over once I’m happy it.
