Size of the Preview window

There is already version 2021 released and the same problems exists.  I’m sick of resizing that window every time I open it. And I open it very frequently. Default size is just too small.

It will always open to the same size. If you've got room on your desktop, you can resize it and just leave it open. But otherwise, every time you open it it will come it at that small size. There's nothing you can do to change it.
