Hey you, GIMP: Be efficient!!
In this time I introduce my pixelart-ready-efficient-gimp-setup!!
Toolbox alignament
To do my ugly pixelart I only need some draw/selection tools, layers, color palletes, and a action history. Because of that, I remove every toolbox and I add one by one!
In the left I put the color pallete editor. Also, I can select the colors from here.
In the right-top I put the undo history (without buttons).
In the right-bottom I put the layer toolbar.
Also, I don’t like having too much windows spreaded in the screen, so I prefered the single window mode (seted in Windows/Single-Window Mode).
Shortcuts and tools
I really hate using the mouse or presing imposible keybindings to use some tools! Thats why I make my own shortcut scheme (editable in Edit/Preferences/Interface/Configure Keyboard Shortcuts).
Resumed Key Layout:
- numbers – tool selection
- qwert… – undo/redo/etc
- adsf… – cut/copy/paste/etc
Because the only things that I do are: Pencil, Erase, Rect-Select, Magic-Select, Undo, Redo, Cut, Copy, Paste… I do the following bindings:
- 1: pencil
- 2: erase
- 3: rectangle select
- 4: fuzzy select
- w: undo
- e: redo
- a: cut
- d: copy
- s: paste
If you have some time, tryit! It’s really confortable 
Preferences details
To improve a few more the behaviour, I setup a few more options:
- Pencil – size: 1 (1px draw)
- Erase – size: 1 (1px draw)
- Erase – hard edge (dont do interpolation, erase only 1px!)
- Preferences/Default grid – spacing: 1px x 1px
- Preferences/Default image – fill with: transparency
That’s all folks! I hope that this info were useless, and that my english use was fine 
Free software for all 

Now Im trying to export scaled images… But it’s late and I have to setup my engine =S
$ convert img.png -scale 1000% img.png
