Hi @giuseppecfgeo​

Thanks in Advance,

@giuseppecfgeo​  Feature Caching (the "magnifying glass" ) has an impact on the performance of your workspace - since the data for every transformer is cached to disc. So Inspector is useful if you only want to check the results if a few places in your workspace, or if you want to compare the results from two or more transformers in your workspace (you can also do this with feature caching by selecting multiple transformers and right click Inspect Cached Features - but might be awkward if the transformers are far apart in the workspace).

I'd like to add to this that using inspectors gives you the opportunity to control the order in which the layers show up in the inspection window: they're sorted alphabetically. So by prefixing them with numbers you can make sure they show up the way you want.

I would like to add this was the way output to view data prior to FME 2018. Many transformers had evolved throughout each release.
