Summary
When adding readers and writers please create more readable and useful names for the navigator.
Details
When you add a reader or a writer the default name is not very useful for example:
<not set> [ARCGISPORTALFEATURES]
I find my navigator is much more readable when I rename the readers and writers something like this:
Esri ArcGIS Portal Feature Service READER
So using the format description not the short name and specifying reader or writer (because after almost 20 years of using FME I still cannot distinguish the reader/writer icons).
