We can now create a new window that does not inherit the current layout. This will be celebrated for quite some time I believe.
In that new window, I may have stuff to do before showing something to the user (finding records, sorting them, maybe even going to preview mode).
The catch is there is no good point to use "freeze window" because we are in a new window where I don't fully control what will be in there at the very first instant.
It would be nice if placing freeze window prior to summoning a card would delay the display of the card until the next event in the card that would normally unfreeze a window.
