Thought of a good idea to take netscan up another level. It would be a pretty big update, so may not hit the next build! I'm thinking of how bookmarks could interact with the application. What if the bookmarks were displayed in an expandable explorer type view down a new left-hand column (A bit like Outlook). Clicking on a bookmark in left column displays the last previous scan in the main results field. If no last scan exists, you are then prompted to Scan the selected network. An additional nice feature would be the option update/append-to a scan results view, so as not to loose previously discovered hosts. Maybe also and option to scan all bookmarks (like an inital discovery mode).
These would certainly add a few extra dynamics to an already marvelous utility. Any thoughts welcome.
