Hi,
in categories and collections, we can select multiple categories/collections at the same time by doing ctrl-click.
For Media&Folders and for the timeline, this is actually not possible.
I would like to see multi-selection for Media&Folders and for the timeline, too, to have a continuous user experience.
To select multiple folders, <Ctrl>+<left-click>. You can only select folders on the same level (siblings).
To select multiple timeline nodes, <Ctrl>+<left-click>.
See the IMatch help for additional information.
