What a great script. Thanks a lot for your efforts.
But I would like to report several issues.
I use the latest version of Firefox.
1. I couldn't see "[My Games] [Open Games] [Coin games]" tab if I don't check the "Fixed Window with scrollable games". Is that normal?
The description and image you provided does seem those tabs will show even without "Fixed Window with scrollable games" checked.
I would really like to use the tabs to switch, but I don't like the fixed window. It makes the window too narrow. I would like it to keep at least the same width as the official default.
2. "Fixed Window with scrollable games" layout is broken.
See the screenshot:
3. What does "Show Open Games Tab in Menu Bar" do? Where is it? It does not seem to work at all.
4. It is better if the "userscript" option is located above sign out. Place it here:
Coins
Points
Account
Friends
Userscript <------------ here
----------------
Sign out
I once moved the mouse to click but accidentally clicked the sign out button. This mistake won't happen if it is above the sign out.
Better and faster accessibility: You first click the drop-down arrow. Then you move your mouse down. It is shorter in distance if you place it before sign out.
