Inverted Thumbnail size slider

[gonefinishing]

As it says in the title, at least my 64-bit 1.4.3 version, running on Windows 11, seems to have the slider in the Filelist toolbar inverted, as it increases the thumbnails' size if I slide it to the left and decreases them if I move it to the right - though the numbers that pop up still decrease/increase like before and in lieu with the current behaviour.

the toggle for thumbnail count vs thumbnail size is not checked?

Doh! Perhaps due to its dark blue color (against the dark grey of my theme), I didn't even notice its existence before. (clever thingy BTW)
I feel like an utter idiot.

Sorry.
