I don't understand the _2 in the naming of these resources.

[jiayl, 2014/03/05 18:19:21]

_2 is used when the consumer of the screencast stream is different from the
extension that shows the window picker. I didn't think of a concise name to
reflect the difference. What do you suggest?

[Robert Sesek, 2014/03/05 18:38:31]

That does seem like a difference that's hard to convey concisely. I don't have
any suggestions, except maybe make the desc="" call out this difference more
clearly?
