### What should this feature add?

In the current flow, drag & drop multiple files uploads them to the Gallery. So far, so good.

Once in the Gallery, selecting multiple files at the same time makes it impossible to drag & drop them into the Canvas in one go. They must be added one at a time.

It would save quite some time if it's possible to add them all at once.

### Alternatives

It has to be done one at a time.
This is a UX / efficiency issue.
