allow setting window title via command line option

[Guest0x0]

Description of the new feature

I mean window title here, not tab title, which is already supported.

Programs like AutoHotKey and komorebi rely on window properties such as window title and window class to identify windows. Unfortunately, all wt windows have the same title (Terminal) and class CASCADIA_HOSTING_WINDOW_CLASS, so there is no way to classify different wt windows (e.g. quake mode window v.s. normal window).

If wt has a command line option that sets the window title to a user specified value, users can classify different wt windows by manually specifying the title when launching wt.

Proposed technical implementation details

Add a command line option --window-title. Any window created by wt --window-title <text> will have <text> as window title.

open question: if an existing window is picked, should we modify the title of that existing window?

Thanks for the request! It reminds me of #4183 and #1320 for various reasons. Decoupling the window title from the tab title and allowing you to specify what goes into that title would definitely be a solution here...

But I'm not sure it's the right one for your use case.

Considering that windows already support alphanumeric window names (which I think can contain spaces 😱), rather than titles, would it be helpful if we just put those assigned names in the HWND title?

We currently only surface them in the tray icon context menu and via the "show window names" action.

Would this work/?

Oops, it seems that I have "showTerminalTitleInTitlebar": false but forgot about it, that's why I get the static Terminal title.

With "showTerminalTitleInTitlebar": true, I can customize the window title via VT title, and that's enough for my case. Thanks.
