This article influenced me quite a bit. It’s where I first heard the idea of “living in your calendar“. It lead me to develop calendar integration for PTM. I also de-emphasized due dates and eliminated task priorities all together.
You can now subscribe to and publish calendars for yourself or a project. I used the open ICS standard, which is compatible with just about any networked calendaring system you can mention.
But the integration goes deeper… You can document subtasks in your calendar as you are doing them. They will automatically appear under the corresponding task in PTM!
