Emacs along with being a text editor, is a battery included software that does more things and architecturally well designed (thus no rewrite last strong). Emacs has good (in-fact powerful) window management, everything as buffer system, self documenting, extensible (upto human brain, maybe DNA?) and every user's Personal development environment.

If you've been a proficient emacs user, you had eventually thought of using emacs to replace tools as well, coming down to only requiring [Emacs, Browser and terminal] in an OS of your choice. This has been many users experience, phrasing as "Emacs for everything" and eventually it being the OS itself.

Even as I was dealing with this experience, I really wanted an Emacs Window Manager, I had used EXWM in X11 way back and was not fully convinced on it (this was before minad took over maintaining emacs-exwm). We really needed it for wayland side, although there was a proposal and some work initiated in 2022 via emacs conf talk, there was no progress. Out of the blue the day came where ezemtsov had posted on r/emacs introducing EWM (use reddit domain if redlib does not work). Its niri inspired WM, and uses smithay library and works similarly.

After it was announced there seems to be another brain-coded emacs window manager using new river protocol (v4) called reka. I tried to compile but was discouraged as reka did not seem featureful and ewm already satisfied me a bit.

Although its pretty minimal it does not ship with every feature niri has. Eventually I made the switch and boy-o-boy it worked well and was pretty stable. I've been daily driving EWM without much issues (although I've opened some issues for enhancements), but basic functionality works, and more than all, its Emacsy!

Emacs already has next-buffer - previous-buffer and tab-next - tab-previous for tabs (workspaces in EWM) to navigate quick. Although consult-buffer is way more quicker. After using ewm I discovered consult has consult-preview-excluded-buffers, and thus I just append all side window buffer to exlude preview, but preview can be so helpful with apps to quickly scan if you've more.

I was using vicinae (raycast in linux) launcher as well, but since most of it can be done in emacs itself, I replaced launching apps/scripts in emacs itself by using call-process or start-process,

You might be interested in reading my EWM config to get more idea. Scroll down to see all functions, I grab firefox history via sqlite-select and show in completing-read to insert a link (Emacsy).

Thanks to emacs window management, every apps (browser, terminal) can be managed as Emacs buffer itself. All I see is emacs frame, and I work in Emacs as its my WM itself now. Now my whole session can be even more customized (embrace Elisp), Emacs (EWM) is DIY Desktop Environment or WM or simply just Emacs itself (what is emacs now?). I no longer quit/leave emacs, if I'm leaving that means I'm shutting down my machine down ;-)
