Similarly to what happens with most MediaWiki logs, please allow filtering the log entries of the translation review log by the type of action performed. Currently they seem to be: change the state of translations and review of translations. Thanks.
This should be as simple as adding ActionFilteredLogs item to extension.json and adding corresponding i18n messages to en.json and qqq.json. See https://www.mediawiki.org/wiki/Manual:$wgActionFilteredLogs for docs.
