Code review comment for lp:~daschuer/mixxx/autodj

Tested r2801 of your autodj branch

* SKIP NEXT button
Does not work as expected. Play-count of the next track in queue is raised by one, but track is not skipped.
* CUSTOM TRANSITION TIME stepper
Changes to the transition time are not instantly effective for the transition from the currently playing track to the next queued track (same for the FADE NOW button). One would expect it works instantly when changed. Nonetheless it works for the next transition.
Furthermore i think the preference dialog is not an optimal place for the stepper. It should go from the preferences directly to the AutoDJ tab in the library widget. This would improve usability and allow easy in-session changes.
