Ranked in these QuestionsQuestion Ranking
Pro Has both GUI and TUI
Both text and GUI versions behave mostly the same, just the way notepad users would expect it to.
Like shift+arrows - select, Ctrl+c - copy, Ctrl+o - open a file.
Pro Small and portable
Has very few dependencies, and very small footprint. Can be copied to a new system in a moment, unpacked and be at your service.
Has a built-in lua engine.
It's available for Windows, Mac and Linux.
Does not have an IRC channel or some kind of forum where a community of developers/plugin writers could evolve around. Has a mailing list which is said to be active but that does not feel that attractive.
