What Hacker News says
4 sourcessway laptop user here (for almost 2 years I think?).
I spent a little while on this, but I migrated from i3, so I just ported every little section of my config bit by bit.
In terms of battery bar and other "bar" type things, I use waybar[0] which basically does all the things you'd expect by default (just install and it "works").
For multi-monitor, config, I initially setup with wdisplays[1] (think arandr for wayland) and then manually copied the positions into my sway config. Monitor positioning was the only thing I needed to setup (and telling it that one monitor was HDPI) and then all of the scaling and everything worked perfectly. This was my biggest selling point for wayland, I now get nice crisp fonts and application scaling works nicely (which was not the case with X).
volume control from the keyboard took no time, just a couple of

extra lines.
There was some stuff to do with the clipboard (wl-clipboard[2]) and screenshots (grim[3] + slurp[4]) that required some setup, but again, just a few lines, and didn't take much mental load.
Oh and I needed to change my notifications daemon(dunst[5]), and chose to change my program launcher to one with a nicer interface and cleaner fonts (wofi[6]).
I think that's all the tweaking that I did. Oh, and I needed to do something with pipewire to sort out screensharing at the start, don't remember that too well though...

You want to use wf-recorder. This is in my sway config:
> set $screenrecord wf-recorder -g "$(slurp)" -f ~/screenshots/mov-$(date +"%Y-%m-%d--%H-%M-%S.mp4")
> bindsym Shift+Control+F6 exec $screenrecord
> bindsym Ctrl+Shift+BackSpace exec killall -s SIGINT wf-recorder
Hitting shift-control-f6 will spawn slurp which lets you click and drag to set the area you want to record. This will then launch wf-recorder and record the selected area, saving to ~/screenshots/mov-${date}. You can use ctrl-shift-backspace to kill the recorder and end recording.

In ffscreencast – a screencast CLI-tool with video overlay and multimonitor support>like I have a script that OCR a region of the screen when I press a button (the coordinates depend of the app that runs)
This is easy to do. Something like grim to take the screenshot of whatever region you want:
https://github.com/emersion/grim
And calculate the coordinates you need by querying the window manager. In sway (i3 compatible tiling WM) that would be:
$ swaymsg -t get_tree
To get a JSON of all the windows currently open and do whatever math is needed.
You can also do a hand selection using slurp:

It works together with grim like this:

Having recently moved from X to Wayland there are still some things missing sometimes but they're not many. If you want a DE at least GNOME and I think KDE as well are making the switch reasonably seamless. And there are some

features that Wayland solves much more thoroughly (e.g., tear free output, fractional scaling). The network transparency part, that is often brought up but rarely used in X is also being delivered:
