Scale plugin regression: having only one window prevents application-level scale

[Chad A Davis]

Binary package hint: unity

TEST CASE:
Start a single instance (single window) of any application (e.g. Firefox). Click on it's icon in the unity launcher.
Expected: activation of the scale plugin on the single window.
Actual: Scale plugin is not activated (presumably because only a single window for the application exists).

If an application has two or more windows/instances, the scale does activate when clicking on the application icon in the launcher.

Approximately a week ago this would cause the scale plugin to activate for windows/instances of that one application. This provides a confirmation to the user that 1) scale is working in general 2) there is really just one, e.g. browser, window open and not another window possibly hidden behind it. This makes me believe this may be a regression, rather than an intentional design decision.

iirc this feature was removed on purpose as a single instance of an app in expose have no apparent usefulness.

[George Karavasilev (kokoto-java)]

Well, the most obvious solution is when the situation is as described on above, clicking on the icon in the launcher should minimise the app. Otherwise it is UX regression, which is not cool :D

[Omer Akram (om26er)]

now in 12.04 the launcher does indicate if multiple windows are associated with a launcher. So the second case which sounded reasonable is not an issue anymore.
