Not finding settings for any of these is what drove me away from GNOME. But i'm always tempted to come back, because GNOME is otherwise very consistent and pleasant. I like that there's utilities i can place in inexperienced hands, for example GNOME Disks to create bootable USBs. But for those non-tech users of GNOME i know, lack of systray and 1D window list are the most painful points.
[0] How are we supposed to teach users to run apps/scripts? I remember long time ago on Ubuntu there was "Open", "Execute" and "Execute in terminal" actions. Nowadays a lot of non-tech people i meet learn to use a terminal just to start Tor Browser, which is not ideal. Is there a simple package i can install to setup such actions?
[1] That alt-tab doesn't consistently take me to the previous window i was on, i find heavily confusing. When i'm switching between browser or terminal windows, GNOME's Alt-Tab takes me a considerable time to reach my previous window because i need to expand the program's group before i can switch. Otherwise, alt-tab takes me to another window that's not the previous window i was on. Can this be configured back to "normal" now?
I'd admit that my windows explorer is tweaked a bit (like using the oldnewexplorer tool) though.
