Hi,
how about add an 'Registration' in main.php which leads to local registration form
this form could collect, of course after explaining and asking for permission:
- number of servers/databases/tables handled with this installation - currently installed versions of PHP, PMA, MySQL - used extension mysql, mysqli - changed configuration (different from default) - used theme - registration information (email, name, company, ... ) - hash of installation path (as unique id for installation) - hash of server connection string (as unique id for servers) - a free textfield for additional comments
this can be stored local, or at least a hash over all, to recognize changes and update registration
and of course in the phpMyAdmin project database
so we can
- make most used settings to default - send security alerts on specific versions - statistics on used versions - and much more ...
