Re: Pointless interface changes ?
The outcome I'd like to see is one that was discussed back when this was first raised: Thunderbird (and Lightning) joins the Document Foundation (i.e. LibreOffice) and preferably takes the other orphan child, Seamonkey, with it. LO would be able to add a mail client and PIM and, if Seamonkey is included, a browser. The interface could then go back to the old style which would better fit in with LO and maybe there'd be money to add in its own CalDav connector instead of relying on SOGO.
