I would like to enter two ideas for future options to this forum:
a) Admin / Scan / failed computers:
currently the overview just shows the date for "last scan on" which correctly only refers to "last attempted scan". There are no additional columns available like "last successful scan date", "failed for X attempts", etc.
b) Admin / IT Assets / Discovery (Network Scan):
in the Network-Overview there is no comment field visible, i.e. just the Network-Range, but no field for the location name. That would help alot if you have a lot of network ranges... to administrate.
Hopefully I could help to bring more features to your software :) I am looking forward reading your comments/feedback about this idea.
