[Plugin: Contact Form 7 to Database Extension] Let an user edit his own entries. /CSV autogeneratio

Hello, first I would like to say: great plugin!

1. Is it possible for a user to edit his own entries? I try to use your plugin for a system where users can put some information on a list to show other users and let them get in contact. A kind of ‘marketplace’ usage.
It would be great if a user can edit his own entries. For example the ‘products availabe’ entry.
(This is just an example, it isn’t a typical marketplace)

2. Is it possible to autogenerate a CSV file everytime a user fills a form?
It would be great because I could combine it with some datafeed readers.

3. Is it possible to show the images instead of linking them when publishing a row/database/particular cell on a page?

Thank you in advance!
