features I'm interested in

• terminal logging
  • I do high-profile tech support, and I need to CYA by showing that I did the right thing.
• better events
  • For more flexible Lua integration
  • the accessibility part of VTE has at least some events available
  • some notes on existing events: [1] [2]
• more thorough API in general
  • for better Lua integration
  • bug 604837 added introspection capability (I'm pretty sure that's this functionality!!)
    • Lua GOI library
    • discussions about GOI: [1], [2]
