I use JabFox to add new entries to JabRef (3.8.1).
JabRef catch the data from JabFox and open a import dialog. The new entrie is added then to the currently selected group.
So before I click on the JabFox button in Firefox I have to go to JabRef and select the group I want. This is time wasting.
It would be nice if I could select the group(s!) in the import dialog.
