Comment 48 for bug 882274

@M.S.#39:

>> Also, there are many GUI elements in ubuntu which toggle show/hide by click without changing appearance (@#20), e.g. most indicators.

>Which indicators are you referring to?

Pretty much every indicator in Unity has this this 'one click: show, next click: hide' behaviour:
indicator for network-manager, for sound, for bluetooth, indicator-me, indicator-messages, indicator for dropbox...
...even the dash and the workspace switcher (button in the launcher!) have this show/hide behaviour.

so for me, it seems to be more consistent, if the other buttons in the launcher also would provide show/hide functionality.

And about my doubt concerning the usability testings:
I'm really curious whether someone could tell me, which change in the GUI caused the change from
october-report:
 http://design.canonical.com/2010/11/usability-testing-of-unity/ concerning multitasking
("Multitasking on Unity is disconnected and difficult at times")
to april-report:
 http://design.canonical.com/2011/04/unity-benchmark-usability-april-2011/
("Multitasking: (...) This is fixed.")

I tested each version of Unity and at least I've seen no change in the way multitasking was handled.
(And multitasking in Unity IS one of those need-many-more-clicks-than-before things which really bother in Unity...)

But after all, I'd like to say:
Don't get me wrong, I'm still a fan of Ubuntu. I'm only confused by its direction change, but now I'm personally happy with Xunbuntu, Compiz and the exelent ambiance design.
Thanks for that anyway. :-)
