Yeah, that's understandable, which is why I'm not currently opposed to staying with Gnome for the time being. However, Cinnamon also had the option to tile windows horizontally, as well as sectioning the screen into 1/4ths. It's not the most necessary feature, but I do miss it when I'm not on the Cinnamon session. The Extension Manager app sounds useful, though I've been steering clear of them due to the complaints I've read regarding their tendency to break. I'll look into it, thanks.
I had a feeling that xfce-notifyd was something not native to Gnome. To be honest, I don't remember installing the Gnome Wayland session, but noticed it at the login screen awhile back. I logged into it using the same login that I use for my LM Cinnamon session; I've heard this is not ideal, and this issue is probably one of the reasons why. For the record, I've also previously tried installing a LM xfce session, so that is perhaps the cause for its appearance. This conversation has me wondering if there's a proper way to reduce any goofy stuff I may have done because of experimenting with DEs. I don't mind looking into it myself, but would also appreciate any insight as you seem familiar with Gnome.
