I'm on the free plan and would gladly pay to upgrade for further features (like the calendar view, etc). But as someone who is a solo user and has no need for any of the extensive collaboration features, the nearly $50/month is far too expensive for my needs. I'll still use the free plan as long as it's available, but it feels like an all-or-nothing proposal right now: give you guys nothing or give you way too much. I'd like to give you something!
