I agree this needs better exposure. The ability to set a group-by (by selecting an attribute) is already filed as PR5763. No idea if and when it will happen though.
It would be a separate item in the dialog I think. Making the name attribute a drop down would be OK - but it can be confusing when drop-down fields also permit a value to be typed in. Users think they have to select a value and don't see the text entry ability. I know Matt doesn't like to do that sort of thing too often. You're right - the transformer help often isn't as detailed as the FFT manual. As a tip to other group members - most transformers are based on a function/factory. If you're really digging for info on how a transformer works then look up the factory/function behind the transformer. Copy and paste a transformer to a text editor to find out what factory it uses - or if there is any TCL type code in there. Hopefully fmepedia.com will have a lot of info of this type that can be edited and updated on a more informal basis. Thanks to Hans and a few others there is already a lot of relatively obscure info on some of the FME transformers.
