Only if simplex-chat had better UI...

What you are describing for the master-sleve layout can be achieved with either, XMonad.Layout.Grid or Tall layout (more likely, other ways to achieve this).

The stack layout on the other hand can be achieved through the XMonad.Layout.Accordion? And if you are not a fan of that you could always refer to the XMonad.Layout.Tabbed.

Extra:

• mirror functionality where you can rotate your layouts. Mirroring XMonad.Layout.Tabbed results in a stack-like layout.
• magnifying glass for your layouts and much more!
• Not a fan of a specific layout and want to adjust it a bit? XMonad.Layout.LayoutModifier is your friend!
• XMonad.Actions.WindowBringer to bring window into focus on demand.
• XMonad.Layout.ToggleLayouts toggle desired layout on specified binding.

Do you have an image at hand that showcases that layout? The only images I am finding from a little DDG'ing are similar to XMonad's XMonad.Layout.ThreeColumns, but I am not sure if that is what you are looking for.

XMonad has most of the features you've listed though: window swallowing, fake fullscreen (other solutions exist: tabbed layout, fullscreen...), xresources (other solutions exist, just not familiar of them tbh), scratchpad, tags, taffybar and many more features in xmonad-contrib!

What about dwm makes it a more appealing choice compared to XMonad? (Excluding the C vs Haskell argument)

Another (new) Emacs user here, I managed to reduce Emacs startup time to 0.6s - 0.5s on my garbage hardware. Some Emacs users have even manages to reduce the startup time to 0.3 - 0.2 seconds!

Also, launching Emacs in --daemon mode makes creating new frames instantanous and because of it you won't experience any form of lag when using Emacs!

A wonderful chat application indeed! Wish SimpleX was built with Material You support though.

At this point, it would be insane to classify it as a text editor only. I personally refer to it as the "Emacs distribution"; a distribution that happens to have its own integrated text editor and other useful tools. But a more accurate description is, Emacs is an e-lisp interpreter and because of this it's a very extensible tool!

More like: "we are too gready to prevent this disaster from re-occuring..".

You forgot one additional picture, "we, together, allow this madness to exist".

If you are an Emacs user, then I suggest you try out Ement.el!

Congratulations to the openSUSE team/contributors for helping maintain this wonderful project! 🎉
