I find rectangle actually preferable to tiling, which I've tried on my linux boxes. Rectangle has the benefits of keeping the application-defined sizes (e.g. the terminal when opened up is 80x20 instead of whatever space is available on the screen) and playing nicely with the system defaults (like command-tab, command-~ to cycle through applications and windows). I find if I ever end up using a public or someone else's device, it's easier to cope; I'm not as helpless without rectangle as I was when I got used to a tiling WM muscle memory.

And the name of Yabai -- which translates to "danger" -- never sounded appealing to me to introduce into my device.

The name Yabai can also be used in a positive sense to mean "great", and is particularly common among young people. Source: https://web-japan.org/trends/buzz/bz0510.html

As a relatively young Japanese speaker, can confirm, it can be either bad or good in context as slang. The comparison to English “wicked” makes sense - could be like “whoa, that’s really uncool/dangerous/awful” or it could mean “whoa, that’s amazing! Sick!” Probably library author is going for the latter!

From what I understand, a more direct analogue to "danger" is "abunai". The word "yabai" almost seems to be usable as a generic intensifier, like many English speakers might use the s-word. (I'm extremely far from fluent, though, so take my observations with a pile of salt.)
