Fails to recognize GNOME Shell 40.rc running
gnome-tweaks-40~beta-4.fc34.noarch
Configuration for dynamic/static/number of workspaces disappeared from gnome-tweaks. The options are planned to be implemented in g-c-c (see gnome-control-center#558 (closed)). However, with options not available in gnome-tweaks, there is no way of configuring workspaces in GNOME 40 from GUI. (The only way I know of is through gsettings keys).
