XnView Software

I just want to drag sliders to change the size of thumbnails in real time.

I know this is possible as I've done it for years, though I'm setting up a new installation of the latest version. I hope this feature hasn't been removed?

you have the slider near path field

Yes, and near to the slider, a button to toggle Size/Number of thumbs.

Ah I found it. You have to go to the View menu and enable the Filelist Toolbar.

I don't want many of the buttons on this toolbar. Is there a way to customise this toolbar, or add this slider to the regular toolbar?
