upgrading webmail ispconfig 3 debian 10

Hi
i recently installed https://www.howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/
is there a way to either upgrade roundcube to 4.11 or to get a better webmail with more functions (similar to gmail functions)

 

is there a tutorial on how to do that?

 

Follow instructions on the Debian Backports repo:
https://backports.debian.org/Instructions/
Install ISPConfig Roudcube plugins to gain more functionality. https://www.howtoforge.com/install-ispconfig-3-roundcube-plugins-on-debian-10/
