Shortcuts for the iPhone’s Action Button ⇥ matthewcassinelli.com
Matthew Cassinelli asked how people are using their iPhone’s Action Button and collected some of the best responses in this post. Unfortunately, I do not see any with download links; if you would like to use one, you will need to re-create it. There are some great ideas here, though.
I have set mine to launch Obscura.
Update: If you are so inclined, you could use it to file bug reports in Feedback Assistant.
