37,000ft is a third-party tool that shows you every milestone, todo, task and reminder on a single page.
I’ve long wanted to see, on a single page, all the tasks required of me across the multiple Basecamp accounts and projects that I’m a part of. I’m thrilled to announce that now, any user of the 37signals products can do just this. And for good measure, you can see all your Highrise tasks and Backpack reminders on this page as well.
There's a full explanation of why the SignalKit team decided to build the tool at Introducing 37,000ft.
