Once you get over the learning curve, there is nothing like LaTex. Here are the best LaTex editors for Linux and other systems.

Official site of MyNotex, free note-taking, document file and activity manager for GNU/Linux.

Notes are gathered under different subjects and are made by a title, a date, a tags (keywords) list and a free-length text. This may be formatted: it is possible to change the font name, size and color of a selected text and of its background, and also to set bold, italic, underline and strike-through; the text may have pictures within it. The software can manage paragraph alignment, bullets, numbered and alphabetic lists with automatic indentation. Each note may have any number of attachments (files of every kind), and has also a spreadsheet-like grid to manage a list of activities which is quite similar to the one used in many software of project management. The various activities of one or all the notes of a file may be shown in a diary view and possibly exported in iCal format. A single file of MyNotex contains various notes filed in different subjects.

There are lots of plugins that do similar jobs to those that I'm going to mention, but I'm not interested in making this an exhaustive list; these are my recommendations based on experience, and they may well change as time goes on:

1. Syntax checking/linting
2. File navigation
3. Keyword searching
4. Autocompletion
5. Tags
6. "Project management"

vim-airline - lean & mean status/tabline for vim that's light as air

I know Vim better than most. Vim was my first real text editor. I used it for years. I helped write the Floobits plugin for Vim. I’ve delved into Vim’s source code to figure out its workings. I even helped write a patch (though it was rejected). Considering these credentials, I hope you’ll accept that I know what I’m talking about.

It may come as a shock when I say: The only good part of Vim is its user interface.

Xournal is an application for notetaking, sketching, keeping a journal using a stylus. It is free software (GNU GPL) and runs on Linux (recent distributions) and other GTK+/Gnome platforms. It is similar to Microsoft Windows Journal or to other alternatives such as Jarnal, Gournal, and NoteLab.

If my latest post on the topic did not tip you off, I am a Vim fan. So before some of you start stoning me, let me present you a list of "obscure Vim commands." What I mean by that is: a collection of commands that you might have not encountered before, but that might be useful to you. As a second disclaimer, I do not know which commands you might know and which one you find useful. So this list really is a collection of relatively less known Vim commands, but which can still probably be useful.
