Analytics app: Customization userid in url, timelimit, rows per page

Hi,
this app greatly expands the usability of NC. I am using extern csv generated by web server and sql query and i have three questions about it.
My reports are user dependent so i need current logged userid in url. I have modified ExternalFile.php, but is there a option to configure it?
Sometimes I am facing timeouts,

Request Timeout

Server timeout waiting for the HTTP request from the client.
what timeout and where should be extended?
I last question is there a option to configure count of rows per page (now it is 10)

Thanks

Hello,
sorry for the very long delay. regarding the userid, this is something that will come in the near future as a replacement variable like %userId% or %userName%

this can then be used in any report
