I did post some time ago about the disappearance of Tilda from Fedora. At the time this was due to the lack of upstream support and the fact that development had stalled. Since then development has again started and Tilda is being improved. While it is not (yet?) available for Fedora it is a simple procedure to add it. The following link covers compiling and installing it. I tested it in Korora 20 Xfce and it worked fine and I have the latest Tilda running now.
