#270 Multiple users support

[Anonymous]

Thanks for your wonderful program.

A very useful feature wuold be the support for
multiple user concurrent modification. we have a
single .bib on a central share and multiple users.
With the current release, it is possible that
multiple users accidentally overwrite modifications
made by others.

Is it possible to add a "lock" feature on single
entries, I.E. when an user open a bibtex entry the
entry is locked?

Or, if it is impossible beacuse of the nature of the
data file, is it at least possible that opening the
file causes a lock of the whole file, so simultaneous
modifications made by multiple users are impossible?

Thank you and best regards
