what i miss hm i say in all two pane Linux managers is this feature.
I cant show total commander-xp expansion cause i don't know how to run it on wine.
But, like this text document i can see all types off images pdfs audios video files, and whats important i do not need to press on every file ctrl+q i just go at one panel from file to file, and second just shows whatever it is that file. Then i have many files this one on windows TC-XP was super, now im forced to use separate programs - and its waist of time, on tc u can doo any bind-key and work super faster :) on Linux well i see only MC and maybe emelfm (but sad is dead ..and emelfm2 just sux..unstable as hell). I did found worker and gentoo fm's they looks solid buttheyrs concept off controling things are weird to me :)
