i can open a custom @window and then set a title for it using /renwin.. eg..

alias heh {
window @window
.renwin @window @window whatever text
}
is there any way to set the title directly when opening the @window?

yes you can
Example

alias windowtest {
window @testing
renwin @testing @test
}]

erm, by directly i mean not using /renwin

I tink you are asking if ther exist identifers off that, right ?
btu that I have knowledge, no.

isin't what /titlebar @window <text> supposed to do ?

No it doesn't rename the window, it adds text infront of the window name.
alias win {
window -e @window
titlebar @window ...
}

The window's titlebar would look like:
[@] @Window ... [X]

The helpfile is deceivingly confusing in this area, as it tells you how to create a @window with /window, and tells how how to rename & title a @window with /renwin, but it doesn't explain how to simply give a @window a custom titlebar-- something that most people would want to do with their custom windows. This is a considerably common question, indeed.

I would suggest that /titlebar @window <topic> be added to the Custom Windows section of the help file, nearby /renwin.
