I like Miglayout and therefore demand it be supported.
Alas, I might do this one myself if I get a little time.
You read my mind. As I was fiddling with GridBagLayout last night, I concluded that mig support would reduce my pain.
Notional support and example added in SHA: 8c6374a.
What do you think? It's consistent with the rest of the API for whatever that's worth :)
This looks great.
