Looking for: Plugin to normalize all tracks together

Has anybody written a plug-in that can normalize every track together? E.g. normalizing 5 mono tracks using the maximum value across all tracks.

For those who may be interested in this subject, there is a discussion of normalize vs. amplify on github here: Normalize tracks [in]dependently · Issue #4272 · audacity/audacity · GitHub

And also as it turns out (learned from that GitHub conversation), Amplify can do this already. If you select every track, apply Amplify, and set the peak to 0db, it will effectively do a linked normalization of all selected tracks.
