should we use a default? I'm not confident this won't break something somewhere.

[jdufault, 2016/03/08 21:37:09]

Done.

[achuithb, 2016/03/08 08:11:45]

should the remove come before fn()?

[jdufault, 2016/03/08 21:37:09]

Done, makes sense because fn() could invoke another screen change.

Is '12345' supposed to be |gaia_id| here?

[jdufault, 2016/03/18 17:38:20]

Good catch.
