Niri is a great system for spawning windows.

But it answers the question of:

"Alright, whenever I want the $app window, I just go to column X of workspace Y"

Which isn't something I want for 99% of the windows I have open.

Most of my app interactions are transient where I prefer "summon $app from the ether without navigating anywhere".

For example, here are low priority apps I have open: calendar, discord, whatsapp, notes, journal, database gui.

Niri would make me find a place to put these apps in the top level and then navigate to them which doesn't match their transient nature.
