Thanks for the response. I am waiting patiently or impatiently depending on my mood of the day. Ready and easy access to my online content will be a boost to my use of Endless. I have Internet(Chromium) setup with a half dozen pinned tabs, which I use for my web apps and I do my general browsing with Epiphany (Gnome-Web).
Gradio screen shots show several buttons in the title bar, that simply are not there when it is installed. I wanted to try installing it on another Linux system to see how it looked before I looked at making a bug report.
Endless calls its file manager Documents, and its photo manger Photos which means installing the flatpak Gnome applications makes for 2 Photos and Document applications on the system. I am not sure why Endless choose to rename Files (Nautilus) and Shotwell. I think it would be best to use the names those applications have long been know by. Calling Shotwell, Photos is not too bad, but Files (Nautilus) being called Documents seems confulsing to me mostly because documents are only a small part of what it organizes. Using the same logic you could have called it Photos, or Movies or Music. In *nix everything is a file and that is indeed what it organizes.
