I've tried many different task management apps over the years. I'd settled into an awkward mixture of apps, each with different strengths. But yours is the first that promises to cover all the bases. Congratulations.

Clearly, apps need to be updated to keep pace with changes and improve features. I'm very much hoping that Doit will continue to develop.

The two main features that I would like to see are conditional formatting and Evernote app integration. When you have many tasks, it is useful to adjust the size and colour according to specified rules. My Life Organized did this well. It's more of a challenge over different platforms, but it would be good to see.
The Evernote integration is a good start, but the link to the website is not that useful, especially when offline. Zendone manages that better, with capacity to edit notes within the app.

You've proven great coding capacity so far, I hope with improvements we can get more people on board and ensure the long term viability of this program.
