Improve user manual page about grouping
On the manual page about grouping, I suggest replacing:
The grouping and ungrouping functions are useful when you want to add or separate audio tracks from video clips, or when you want to create a block of clips that you can select, edit and move all at once.
Pitivi allows you to combine:
- audio and video into clips, and
- multiple clips into groups.
This means you can edit multiple pieces of media together, e.g. applying effects together, or moving along the timeline together. This section shows you how to group and ungroup audio and video tracks within clips, and also how to group and ungroup multiple clips together.
