I would like to see the inspector far more integrated with the FME Workspace. Use the results inside the inspector to guide and insert transformer in order to clean data. There are lots of simple but tidies data cleansing tasks that could be discovered and cleaned while you analyse and view the data. For example removing/replacing strings. Split or concatenate strings, find/replace text, change projection, date formatting, aliasing, data type conversions, etc... The inspector could give hints while users simple select text in the result or selects attributes... The inserted transformers (suggested by the inspector) would basically be inserted in the work-space after the inspector-transformer that exposed the results.
Such radical changes could allow FME to come a step closer to basic users and it gives advanced users a quick tool that would improve building work spaces much faster. Even cooler would be to re-run the last result so you instantly see the effect of the added transformers...
