The only annoyance. You have to start the application first to attach it to the dock so that it remains as a starter. This should be done directly in the desired order because you can not sort the starters afterwards. At least I haven’t managed to do it yet.
Now I just ask myself; Who has already known about it and did not let me know?
Or, why was I too lazy to look on the page of XFCE again?
Since I didn’t find a category Off-Topic, I post it here.
Thanks for the links.
Since the SocialChannels over IRC/Matrix or others are nothing for me I find the link to discussion.fedoraproject.org interesting. Whether one reaches there with contributions so many people as here on AskFedora I doubt however.
Maybe I write a few suggestions for improvement in the channel provided.
