Closed requested to merge dannyT2018/pitivi:timeline_interval_release into master
Currently, there is no way to to focus on a specific part of the timeline with editor-friendly features.
For new features that want to improve editor workflow, there is not a good way to focus on a specific part of the timeline. The task of implementing a new feature is more daunting than it needs to be.
To solve this issue, we have developed a way for users to create an interval selection on the
ScaleRuler using mouse or keyboard shortcuts that is persistent between editor actions. To show how much easier it is to implement new editor-friendly features using our feature, we have also implemented looping for the selected interval.
Closes GitLab issue #1842
