I think a good idea would be to create a reporting module on the admin side that allows the creation of in-depth reports via a drag/drop interface utilizing the existing device data, widgets, and files on tago.
You could utilize the already created widgets and drag/drop them to be inserted and then saveable as a pdf, excel, or any other format needed. Drag and drop would allow for easy formatting, sizing, and creative placements with widgets the run users are already familiar with looking at. The same goes for files saved in tago
This would make this application much better!
