Comment 1 for bug 1407527

Any progress on this one?

- The column could be read-only in the first step -> BrowseTableModel::flags()
- For displaying values like "-5.43 dB" you can use ReplayGain::formatRatio2Gain() that has been added recently. Please note that TIO::getReplayGain() despite its name currently stores the internal ratio value and not the track's dB gain.

Background: I need it together with a new context menu option to reset a track's replay gain for effectively evaluating https://bugs.launchpad.net/mixxx/+bug/1407010
