Please add find and replace to the Project Panel

It would be great to be able to find and replace text strings in columns in the project panel for batch editing of sequences, clip names & metadata. The use cases for this would be:

1.  When duplicating and renaming new versions of edit sequences
2.  To rename selections of clips or sqeuences
3.  To batch-update metadata in visible columns in the the Project panel

It would be useful if the find and replace dialog had checkbox for 'selected items only' - and if I'm being greedy - a preview of the update, and if I'm being super-greedy: regex support.
