This is a suggestion to the plugin's author.
Would it be possible to add more special tags such as country, browsers used, operating system etc. of the sender? It will be very useful!
In addition, is it possible to "grab" a custom stylesheet for the contact forms in the active's theme folder? It actually makes upgrading easier because currently any changes made to the plugin's stylesheet will be override whenever there's an update.
Thank you so much! :)
