https://github.com/vdepizzol/gnome-shell-extension-overlay-icons Can we get this extension added to the list of current ones. I know my users would really benefit from this one.
This extension is not part of the "official" GNOME Shell Extensions delivered by the GNOME Project, so there is no reason to merge it in the current gnome-shell-extensions package. The only acceptable way to achieve this goal would be for you to convince the author of gnome-shell-extension-overlay-icons to submit his extension to the GNOME Project. If you are a Fedora packager, you can package them... Or try to convince another Fedora packager to package it ;-).
