Financial support / donations
Is it possible to financially support you outside of becoming a premium user? I can't find any Flattr/PayPal/other support or donate button anywhere. I don't like fixed prices, but I like to support good projects. I would be willing to send you some money from time to time. I guess I wouldn't be the only one.
Please consider it. For many people $30 a year might be a bit too much (not everyone is US-based, after all). But they still might not want to use Todoist completely for free. However, there's no third choice at the moment. Either $30 a year, or $0 a year. I think you're missing out on the opportunity to receive at least some money from this group of people.
