But if you're looking for something that's much more simpler than that, that which uses less resources, then Leafpad is the one to call for :). Leafpad actually comes as a part of the LXDE desktop (a light weight desktop for GNU/Linux) and in comparison with Gedit or many others, it has very little options (no preference window at all), one of the fast loading ones + uses very little system resources as well.
*. Running more than one instance is supported (new windows), although tabs are not implemented there, yet which would have been nice otherwise.
*. Search and replace words/text.
*. Change font, word-wrap and display lines.
*. Cut/Copy/Delete and Undo/Redo ability.
*. Auto indent.
*. Open and save in few different file formats.
*. Print preview (and send to printing from its window).
*. Drag-n-drog support.
That's about it. You can't change the background or any other look-n-feel of the text editor but for its purpose it's quite good, I guess.
You can install leafpad text editor in Ubuntu 11.04 Natty Narwhal, 10.10 and 10.04 by using the below command in your Terminal window.
sudo apt-get install leafpadBut as said, remember, this cannot fully replace Gedit or Kate (Qt/KDE's text editor) for instance because of the lack of few minor options but that being said, if you're looking for something that's fast like hell and minimal distractions + low on resources, then Leafpad is something worth giving a shot :). Enjoy!.
