I have quickly searched the forums, and may have missed this - but is anyone interested in making a launcher for the freeware contact manager, Open Contacts (http://fonlow.com/opencontacts/)
There is a portable version on the author's website, but there appears to be some incompatibility between a USB key portable implementation versus an installed version on the same desktop. I suspect that the portable app is accessing the registry entries. Not really obvious until a fresh Outlook contact data import is done. There is some risk that the old/new copies of contact data get muddled. I have removed my desktop version and only use the portable USB key copy to ensure that I have a single source of contact data. This is simply an artifact of the author's portable implementation I believe.
Anyway, while the app has a clunky looking GUI, it does sing like K D Lang on a good day. Superb Outlook data import, and a good range of import/export options.
I really like this app, and have found it to be the best open source/freeware contact manager I can find. I use it as my primary portable contact manager now, and see nothing better out there. It is extremely versatile, and very robust.
I suspect the difficulty in making this fully portable will be low. Anyone interested? It should prove to be popular. It's crying out for a launcher!
