Feature Request or How to for Inventory

I'm not too sure where to put feature requests. So, here we go.

1. Alerts. If a server goes offline, I want to know about it. Or if a hard drive is about full, I want an alert about it.
2. Integrate something like windirstat into the program as a scan option. This way, if a target server or computer is almost full we can find out how and where it's almost full at.
3. The ability to monitor shared drive space on any shared drive. Currently, we use a PowerShell script that monitors all the shared drives. I would like to be able to do this from pdq and have more in-depth results.
4. Geo Location of agented computers.
