You like latex but won’t use a text-editor because you’re tired of memorizing all those crazy latex-commands?
Then try Texmaker! This tool is a simple frontend for Latex-Interpreters like LiveTex or MikTex (Linux/Windows)
You can reach the most commands using the menu or some shortkeys. A preview using the inline-PDF-Viewer is also possible (it even jumps in the preview to the section on which you’re working on)
Let’s have a look at this wonderful piece of software. it work’s like a charm on linux and even windows (using MikTex, packages can be installed on the fly)

You know/like tools like Norton-Commander, Total-Commander, Midnight-Commander or similar file-managers?
All these managers support the classical two-panel style (which is very powerful by the way) You can handle all your file-belongings in a very intuitive and fast way.
The most popular Linux-variant, which is running under X, is Double-Commander (Midnight-Commander is the one for the console as you already know) Double-Commander works like the famous Total-Commander (which is still alive!)
See http://doublecmd.sourceforge.net/ for more information.
Aseprite is an old-school Pixel-Editor which is very useful even when you’ve to create some kind of animation.
It supports multiple layers, shading, brushes, tiles and much more.
The user-interface needs getting used to but that’s just a matter of time.
Pixel-art can be fun for everyone, not just game-artists, software-developer or geeks, so have a look at http://www.aseprite.org/ (Their website is quite informative)
