Pick this for a self-contained operating system with no external vendor account: everything in Solo Command Center (today's schedule, open commitments, stalled projects, recent notes, meeting prep) plus an email outbox, so inbound mail is captured into tasks and commitments and replies can be sent. Built entirely on Recued's own tasks, notes, and contacts — add a CRM, billing, or GitHub pack later when the business needs vendor depth. If you don't need the mail outbox yet, Solo Command Center installs the same daily cards without it.
