There's a handful of OpenType features, including ligatures and alternates:
Ligatures for ff, fft, ft, tt, gj
Alternates are grouped into stylistic sets:
1. An alternate u, possibly more legible, but definitely not as much fun!
2. Again, a more boring version of m, just in case the default is ambiguous.
3. A more exuberant L
4. A blackletter informed T
5. Alternate P and R
6. An alternate 1 (one)
