> With a tiling window manager, every window you open has cognitive overload. Which workspace, which location on screen, is it okay if other windows resize, or do I have it float even? Every tile you add affects the other tiles in some way - at the very least a new tile (e.g. on a new workspace) consumes space that cannot be taken by other tiles. The reward for this additional cognitive load is that every action is concious - reducing a lot of the mess that can pile while using a comptuer. This makes them incredibly suitable for people whose computer use is predictable, organized and focused on quick parallel tasks. I understand why so many developers use them.

This is not true, at least not in i3. When I don't want to think about how to position a new window I can simply switch to tabbed or stack mode, where all windows inside a determined workspace will be "maximized", and I can switch to them by changing the tab (mostly like browsers and web pages). This isn't really much different to Alt-Tabbing, except that I find more efficient (of course, this last part is IMO).

It is true that on my current setup almost all workspaces have a specific usage, however I have a "trash" workspace specially created to put those things that does not make sense in any other workspace. This workspace generally runs in tabbed mode thanks to above.

> With a tiling window manager, every window you open has cognitive overload.

I've been using a tiling window manager (XMonad) for ~3 years now; this is definitely true for the first few days (or weeks/months) until you adjust. After that, there is less overhead as you become more familiar with how the window manager behaves.

But this is also true for stacking window managers.

> With a stacking window manager, the cognitive overhead of opening a window is much less.

I think the level of cognitive overhead involved comes down (in the case of tiling window mangers) to what window rules you have, what kind of bindings you have set up to navigate between windows, etc., and how comfortable you are with those rules and bindings; the less comfortable you are, the greater your cognitive load will be when trying to use them.

Again, this is also true for stacking window managers.

> Every new window on the stack doesn't affect the others you were using.

Unless it "steals" focus and blocks the window you were working on. But that's expected behavior in a stacking window manager, so it's not much of a disruption. And it's one a user will certainly be aware of when opening a new window.

And this can (and usually is) be true for tiling window managers as well.

> I see a lot of people that respond to you by appealing to some objective superiority of tiling window managers, but there's advantages and disadvantages to both.

Right. There are pros and cons to each and really, but most people just don't really care that much about what window manager they're using.

I do want to add that one of the biggest pros to a tiling window manager (and a few stacking WMs) is the amount of customization available; if you're using a WM like XMonad, i3, Sway, bspwm, herbstluftwm, etc., you can configure the WM to do basically anything (including behave like a stacking WM), while many stacking WMs are fairly limited in how much customization they can have.

But that makes the assumption you're interested in customizing, which not everyone is.

What I've been thinking is, why can't we have both? Imagine just two changes: a workspace's mode can be switched between tiling and floating, and additional workspaces are just windows. Now you can have any combination of floating and tiling that makes sense to you. You could, for instance, set your desktop to tiling mode and open two new workspace windows, the switch one to floating and run your GUI desktop stuff on the left side of the screen and several terminal tiles on the right.

I think AwesomeWM allows that

I used awesome for a few years and while I think you're correct to say it does try to do both, in reality it ends up doing neither very well, IMO.

This is the mode how I run Windows with WinSplit Revolution.

It doesn't change anything by default, but with alt-keypad I move certain windows to the upper left, upper right, bottom right, bottom left and so most open applications have their exact position, but everything else is floating.

I guess I'd use a full blown tiling WM if there was one, though, I don't really see any downsides once you configured it to your preference. So bad for new machines, good for regular use. (for me).
