I'm looking for a lightweight freeware text-editor for linux (Ubuntu) with two (or more) code panels, so I can compare pieces of code side-by-side.
For Windows Notepad++ has two panels, and I can even edit the same file in both panels, but there's no linux version AFAIK.
In Linux I'm using Geany, preety good and lightweight, but it hasn't two panels (AFAIK, again).
What do you suggest? (Maybe can be useful: I'm working with Ruby.)
I just found a plugin to Geany called "Split Window". But it's not "so perfect". Only one file at time can be at the splitted window; it hasn't its own tabs group.
