Now, if I click an mail-address in Contact, a window for a new mail opens. If I want to see the existing conversation from/to this mail-address, I have to go to E-Mail > search message and start a search "from" and "to" this mail-address (or "somewhere in the mail-header") in "all folders". It would be fine if this search would be automated after clicking the mail-address. Alternative: add a choice in the right-click context menu beside "copy e-mail-address". Reproducible: Didn't try
