Auto Layout
Because SourceTreehas continued to support versions of Mac OS X back to 10.6 (Snow Leopard), we’ve still been using the ‘springs and struts’ approach to user interface layout up to now; we couldn’t adopt the newer Auto Layoutwithout restricting support to 10.7+. So I’ve only just started experimenting with Auto Layout recently, and I ended up getting stuck for a while on something that seemed like it should be really simple, and yet I couldn’t find any hard information about it on Stack Overflow or via Google: how to specify tab ordering.
