Hi,
I would like to add a few more thumbnail size options to nsxiv.
On a 4k screen, the biggest thumbnail option is still too tiny.
I added thumbnail sizes up to 320px which makes the thumbnail view
usable again (still tiny on a laptop 4k screen, but usable).
Personally, I'd go higher (to 640px), but nsxiv creates a thumbnail
cache in .cache/nsxiv, which stores previews at max-thumbnail-size.
I think 320px is a reasonable compromise.
You can test this in a folder with images:
$ nsxiv -tr .
Then increase the thumbnail size to max by hitting "+" a few times.
Comments/OK?
