I sent a pull request to Vladimir on github about my mods on recipient_to_contact.
As I said now users can select a firstname, surname and a group when they add new contacts. By Vladimir's suggestions I made firstname, surname and group not required, so if someone want to add a contact quickly he still can.
I also added a "Save" button in the dialog box.
I used the last version released by Vladimir, so we could not have problems with keyboard_shortcuts.
I'm reading now what rosali wrote down...
I will correct the problem with roundcube 0.5 soon as I can (I was really busy because of my job) and I will check the problem about duplicates. I thought that the api function insert take care of duplicate...maybe I didnt understand what rosali would say
.
Actually plugin has another problem: global_addressbook plugin is not compatible. I will solve that soon as I can.
Again thanks to Vladimir for his kindness.
Ps. any test/suggestion is really desired!
