I think it would be great for UX to add this features to Fleet UI: 1. In "New Query -> Select Targets" allow searching by IP address + allow selecting IP range with CIDR. 2. Search function in Hosts. 3. Add "Last Seen" date to hosts. 4. Grouping hosts. (Labels really suck)

Searching via CIDR Could be interesting. Would help with service discovery and help audit if hosts are in the right subnet
