#238 External String Files

[comcreate]

1) Is it possible to link some external string files
so that bib preview can display the actual string
(instead of the string name) in the preview window?

2) Is it possible to add a pop-up window so that it
can pop up and let the user select a string from a
list? WinEDT has a similar function that if the .bib
file is also opened, typing in "\cite{}" will pop up a
window, let the user select a citation entry, and
insert it to WinEDT and complete the citation. People
could not remember all the defined strings and this
feature could greatly helps users.
