Please consider:
- Transform selection - without transforming whatever is selected, with input: selection position and width/height (rectangle containing selection).
- Bug?: Selecting multiple groups opens grup selected as first.
- Groupng groups (or groups and layers)
- It says merge two layers even if you select three or more
- Merge group and merge layers?: Can it be only merge selection? So you can merge layer and group in the same time.
- Grid
