An on-call phone system for small healthcare practices. Patients call the practice's normal number, the shift schedule decides who is covering, and the clinician's own phone rings.

• The on-call rotation is the routing, not a forwarding chain
• Patients install nothing, clinicians need no app open
• Voicemail, call history, and contacts kept by the practice

A Chrome and Firefox extension that groups new tabs with the tab that opened them. Configurable naming, group size limits, custom rules, and a blacklist.

• New tabs join the tab that opened them
• Five naming conventions, two grouping modes
• Per-domain rules and a blacklist
