Freshsales gives you 3 sample custom views,
1. Active - Lists the contacts with lead scores greater than 70.
2. Inactive - Lists the contacts with lead scores between 30 and 70.
3. Slipping Away - Lists the contacts with lead scores lesser than 30.
The best part about custom views is that you can edit them, delete them and create as many views as you like with no restrains.
