Krusader (best KDE file browser/commander/multitool
)suports KIO slaves, It has built in editor which is the best I found in linux world (because of my work aspects > web developer it is best), this editor let you edit files "onfly" which is better even than totalcommander + vim combo for me. (accually it stores temp files and send then in background while save).
Krusader let you also use external editors like sublime editor BUT it doesnt support remote editing (KIO slave).
Maybe someone can write down some plugin for sublime for this functionality, IMO krusader + sublime editor would be best COMBO in linux/KDE world, especially for someone who works simillar like me.
Pleanty of ppl are asking about best twinpanel manager and editor working with it.
