I want to both

• move my irssi window to a specific workspace


• remove the border and title

Before I removed the border I had

assign [class="^kitty$" instance="^__irssi__"] → $ws10

This worked great, but now I want to remove the border so I add

for_window [class="^kitty$" instance="^__irssi__"] border none

That does exactly what I want, but I can drop the assign and just have the for_window with,

for_window [class="^kitty$" instance="^__irssi__"] move to workspace $ws10, border none

I know the i3 docs say this about for_window,

The difference between assign and for_window <criteria> move to workspace is that the former will only be executed when the application maps the window (mapping means actually displaying it on the screen) but the latter will be executed whenever a window changes its properties to something that matches the specified criteria.

But that doesn't seem to provide me any guidance when I don't care about that. It also raises the question does anyone really care? It seems like assign protects you against a window that both,

• Changes properties after initialization


• Would otherwise trigger a rule after one of those changes because you could not make the rule more specific to exclude the window's new properties?

Am I missing something here? I just have a feeling like that's a very small use case and I must be reading it wrong. Should I care about this difference? When would I care? And what should I do here, have an assign and for_workspace, or just merge them into a single for_workspace?
