I think it would be nice if we could select a bunch of requests at the same time (with shift or ctrl just like in other software, too).
The request preview on the right could then show a maybe colored hint on the top saying e.g. "23 Requests selected - only last selected one shown below"

Benefits:

• deleting of multiple selected requests at once should be possible
• pin a bunch of request at once
• would also be nice if we could export an HAR file from just the selection
