I think that fUniqueID and fBits in TObject is not useful to store in TTree.
I found in ROOT users guide that we can disable that with
MyClass::Class()->IgnoreTObjectStreamer(); 
.

If you also think these are useless information, please implement it in ROME.



second topic.
This is just a matter of favor.
We sometimes use TTree interactively. At that time, I feel fRunNumber, fEventNumber, fTimeStamp, 
fSequentialNumber are long to type.
I prefer shorter without upper case letter.
If many people agree it, I would like to ask to change them run,event,timestamp,number like MIDAS analyzer.
