Backend should show info on frequent users and/or booking statistics

Currently there is no 'automatic' way to find users that book the items very frequently.

I suggest to create a page in the Backend to show a list of the top 50 (?) users with confirmed bookings, sorted by the number of bookings.

In the best case, those information could be accessed for different time frames and items. E.g.:

• Last month
• Last 3 months
• Last 6 months
• Last 12 months
• Since the beginning of time
• Per item
• Over all items
• Per location
• Over all locations

In addition to that, booking statistics by item and/or location could be nice.

I am not sure whether a single page is really able to meet all requirements. Therefore it could also be an option to include a way to export booking data, maybe as a CSV? Then the CSV could be opened in any spreadsheet tool and be analyzed in any desired way.

Format: CSV

Colums: Itemname, Locationname, Username, user ID, Booking date, Start date, end date, booking duration, booking status.

Of course an existing plugin could also do the trick, does anybody know one that works?
