Counter showing how many clips are selected when using multi-select in Paste.

Request:
Add a visible counter showing how many clips are selected when using multi-select in Paste.

Rationale:
When selecting a large number of clips, there is no way to confirm the current selection count. This makes it harder to manage bulk actions and verify that the intended number of items has been chosen.

Desired Outcome:
Display a real-time clip count whenever multiple clips are selected, so users can quickly confirm the number of items included in the selection.
