I suggest adding Fabric support to fuse so we can track the crashes and what lead to crashes. It would be awesome to not have to test the apps over hundreds of possibilites and try to find small bugs.
Crash-reporting and testing frameworks are definitely on our list. There seems to be several popular ones out there though, so always good to get some user input on which ones are most desirable. 
That said; it’s not the first thing we’ll get around to releasing so if anyone out there feels like having a go at integrating it using foreign code that’d be very interesting!
