I use Ironfox and Fulguris (for when something doesn’t work in IF). They’re both good. Ceno is also interesting for its p2p/ anti-censorship features, although it’s slow when not on wifi.

This is a frequent source of frustration for me, too. Can’t even tell if it’s cli or gui a lot of the time, based on the documentation. If I could just see what it looks like, I’d have a good idea right away of whether it might meet my needs.

My hate comes from wanting it to work like LView Pro. There’s no Linux image manipulation program that comes close to meeting the standard they set in 2001.
