I’ve toyed with tiling on GNOME as well. It’s a fantastic feature when you can easily toggle it off and on.
I don’t often use tiling on my laptop, it doesn’t usually do what I want at the time, but it’s really helpful when I’m plugged into a couple of 32in 4k displays.
I find it leaves me with too many odd sized windows that aren’t terribly useful. I think it’s one of those things that bother some people and not others 🤷♂️
For example, the terminal along the bottom in OP’s screenshot wouldn’t help me all that much, it’s too small for me to do much with unless I’m just looking at a very small piece of a log or a very small status display. Most of what I run tends to be about the size of the window in OPs upper right so I just stack and use the GNOME overview or super+tab to switch. I find the GNOME overview model really, really helpful.
I wouldn’t mind laptop tiling if I could have windows that maintained their size and (relative) position on screen but shrunk down to a miniature version when they weren’t focused. Sort of a hybrid between an overview and tiling, where the window expands to it’s original size and position when focused.
This did come through by the way, but it took an extra 15-20 minutes before the comment would actually load in my client. I got the reply notification immediately but couldn’t load the comment until a bit later.
