Sorry, it is already committed. I was looking for a commit hook message or a "Ship it!" message.. Guess it was "silently" committed. It can already be found in the current 4.7 codebase.
Sorry for the noise.

This source provides such information about current Mixer as: it's readable name, is it opened, its balance and list of available controls. It also adds basic sources for every control, which provides only information about its readable name

> All works fine except the one thing. When I request an source for Mixer, it also adds soucres for controls. And then when I request source for already available Control, it doesn't react anyhow. But when I set "Update every % ms", and click "Reqeust", it works fine. If I request a source for control BEFORE requesting the source for mixer, all works fine too (without setting "Update every % ms"). I don't know is it a plasmaengineexplorer bug, or my.
