Is there a way to add a "new email" counter/badge to the Evolution app icon on Ubuntu Dock? The Thunderbird icon shows a badge/counter/indicator with the new resp. unread messages.
Ryan Hendrickson and Milan Crha have worked on this and it should arrive in Evolution with version 3.29.3+. Thanks a lot!
Hopefully this will be backported to Ubuntu 18.04 although I have my doubts.
Update 2019: No backporting yet. It looks we have to install a newer Ubuntu or Evolution version to be able to use the updated Evolution with the "new email" counter/badge 😔.
Ubuntu 19.04 (and later) comes with Evolution 3.32.1-2 and the counter/badge works.
You may have to install the package
evolution-indicator if it is not installed by default, e.g. with Synaptics or in a terminal:
sudo apt install evolution-indicator (Thank you Cos64 for the tip).
