From 2df3a079a060bb56aaa4d94df066936cb7b73f9d Mon Sep 17 00:00:00 2001 From: Bence Ferdinandy Date: Thu, 2 Feb 2023 19:39:58 +0100 Subject: templates: add initials function When listing all addresses with names, in for example the To field, one might end up with a very long string. Add the initials function, which extracts the names from addresses and then shortens each of them to the initials of the name.
