I would like to enable this feature. Is there a way to do it?
Topic on Talk:Compact Personal Bar
For some reasons, this product is discontinued, so if you ask how to enable it on a wiki maintained by WMF, the answer is: you can't do it :(
The reason is pretty simple: No one has the time to maintain it :/ If you, btw., be interested in doing some work to bring it back, I think there would be some very happy people (including me) :P
How much time have WMF developers spent working on projects that turned out to be discontinued due to 'lack of time'... Ironic, isn't it? Yet CPB is/was charmingly useful and many of us want it to be back. Anyhow.
