Since FME 2018 there are Quick Filter options in the translation log (https://community.safe.com/s/bridea/a0r4Q00000HbrcEQAR/translation-log-quick-filter). This has been a great improvement, but I'm still missing a more general filter where you can type in any keyword like for example a transformer name, an attribute that is causing trouble, etc. and see only those messages in the log. Basically the same as in a job log in the FME Server
