The bug

Scenario: From the AppLoader (webpage or Gadgbetbridge) it is not possible to know the amount used/free storage memory, and I consider this info important and useful for end users.

Expected: In the" More" page and under "Device info" section, status about memory can be shown.In

Workaround: Open web IDE and execute require("Storage").getStats()

I'd be happy to merge a PR that added that functionality... I guess you could do a percent bar with used+trash+free shown
