That's a good idea and is on our list for v2. To do this, all data will need to be in a DB backend. This will also allow keeping or "reloading" the previous scan data. More importantly there will be automated scanning, so new devices on the network get scanned and everything is kept up-to-date. Because of this, you'll most likely wish to run Slitheris 24/7. We plan to release details of version 2 as they become available, but rest assured it will be a free upgrade since everyone receives Free Lifetime Upgrades.
