A better differentiation analysis
Better work out that really only text changes and not some cryptic technical random numbers run into the analysis. (For example cache busters from CSS files)
Weekly update emails
Instead of daily emails about every change of a page, we could also send weekly aggregated update emails about all changes of the entered websites.
add a comment
With a custom field comment, I can insert (eg) my ID, so we can import the change easy in a db with ID referral.
Ready-made scrap type (LinkedIn)
We can monitor all open positions of a company on LinkedIn with ready-made scrap types.
