Browse Source 
* Fix multiple instances running

* Make ColorPicker invokable from the runner

* Use a local mutex

* Enable running ColorPicker as standalone as well as a in PT

* Add some logging

* Remove newline

This will happen sooner or later and is not needed in the PR

* Update mutex name

* Update names

* Add logging
