Trying to get a window container within another window about microui HOT 3 CLOSED

After some fiddling, it seems this is by design? The reason I was asking is I wanted to be able to set a window to open while within another window/container. So it seems you can only get a container if it's already within another parent window AND only if the call to open the window and the actual begin_window call are on the same stack level so to speak. So I can't do something like:

if(mu_begin_window(ctx, "Parent Window", mu_rect(200, 100, 300, 400)))
    {
        if(mu_begin_window(ctx, "Child Window", mu_rect(200, 100, 300, 400)))
        {
            if(mu_button(ctx, "Open Another Window"))
            {
                //Won't work because this mu_get_container call is done within "Child Window". You would have to move this button up a level to the parent window
                mu_Container* cnt = mu_get_container(ctx, "Another Window");
                cnt->open = 1;
            };
            mu_end_window(ctx);
        }
        
        //This window won't open even if above button was pressed
        if(mu_begin_window_ex(ctx, "Another Window", mu_rect(300, 100, 300, 200), MU_OPT_CLOSED))
        {
            mu_end_window(ctx);
        };
        
        mu_end_window(ctx);
    };

Yes, this is by design. All window references inside a window are unique within the context of that window; this makes sense in the context of having nested sub menus (eg. imagine you have many entities each with their own window, you would want all children windows spawned from these entity windows to be unique to their parent). This means for the case you described you need to defer the opening of the window to the context of when that window is processed:

if(mu_begin_window(ctx, "Parent Window", mu_rect(200, 100, 300, 400)))
    {
        int open_other_window = 0;
        if(mu_begin_window(ctx, "Child Window", mu_rect(200, 100, 300, 400)))
        {
            if(mu_button(ctx, "Open Another Window"))
            {
                open_other_window = 1;
            };
            mu_end_window(ctx);
        }
        
        if (open_other_window) {
                mu_Container* cnt = mu_get_container(ctx, "Another Window");
                cnt->open = 1;
        }
        if(mu_begin_window_ex(ctx, "Another Window", mu_rect(300, 100, 300, 200), MU_OPT_CLOSED))
        {
            mu_end_window(ctx);
        };
        
        mu_end_window(ctx);
    };

Thank you for the explanation. I'm not very familiar with ui stuff so sometimes it's hard to see the 'why' for some of the library design. Appreciate it.
