In previous versions, I had resized the preview popup to be a suitable size for me, and that size was remembered. It's especially important for me, since I have a trigger that automatically shows the preview popup every time I copy anything to the clipboard. So, I see the preview popup sometimes hundreds of times per day.

Now, in version 6.3, the ability to remember/save the size of the preview popup is no longer possible.

For text that is copied to the clipboard in Version 6.3:
The preview popup can be resized, but it doesn't remember that size. The next time the preview popup is shown for text that is copied to the clipboard, it goes back to its default size, which is too big for my purposes.

For images that are copied to the clipboard in Version 6.3:
A different size preview popup is shown for each image, seemingly according to the dimensions of the image. Several versions in the past (before the long drought where image previews didn't work at all) image previews would fit into the size of the remembered/saved preview window. I would prefer that the size of the preview window I've configured is remembered and respected, such that each image preview fits into the size of the preview window I choose to use. I don't want a different-sized preview popup window each time.
