[M4IF Technotes] GUI editor for BIFS text files?

[Lyndon J B Nixon]

I can third that :)  I would think BIFS is not intended to be the format 
in which files would be manually edited,
for that you should look into using the XML representation for MPEG-4, 
'XMT' (which comes in two flavours. If
you want to remain close to BIFS, there's XMT-A, and for a more readable 
and more abstract syntax which is much
like SMIL, there's XMT-O.) Then you can utilise any of the multitude of 
XML editors out there.
There is also reference software to transform from XMT-O to XMT-A, from 
XMT-A to BIFS and to encode
XMT into a mp4 file.
