I think one really interesting feature for making a difference would be the following:
A new auxiliary program at BaKoMa aimed at creating customized bibliographic sytles (.bst files) for
being used with BibTeX and/or Natbib. It should be easy to use, maybe with visual features... I mean,
it could be like a friendly visual interface for `makebst` command program provided by `custom-bib`
package, or something similar.
Also, it could help somehow to choose the cite style, I mean, it could work as a guide for choosing
appropriate Natbib package options, or something similar.
I think this is a very interesting feature because managing bibliography is one of the hardest tasks
when managing with a LaTeX document, at least for me, specially if it is a big one.
