__NOTOC__thumb|10000px|right|Toolbox from GIMP 2.6
GIMP has a "toolbox" to quickly perform basic tasks. Toolbox is customizable, this means that you can add / remove any tool you want. To select tools for doing something, go to the "Tools" menu, and select any tool you want. To put the tool on the panel go to "Edit > Preferences > Toolbox".
But it can only be edited in a linear way, that is, while sorting it in the "options" there's no way to see where tools will finally appear on the grid. Even though the program's layout updates instantly. They push each other around. There's no way to align tools to right or other corners, or each other.
If the user later shifts the width of the toolbox' panel (to optimize space on screen), the grid gets misaligned, so there's a way to accommodate only 1 layout.
If leaving a not evenly divisible quantity of tools, the lowest-right corner can't be utilized.
For that matter, it may be useful to make a screenshot of the toolbox with having activated all the needed tools, and lay out the grid in an easy raster program like Paint or GIMP itself, to make the surface look the needed way. Then start moving them in Preferences accordingly. Remember that tools go from the up-left corner, rightwise then down.
By default not all tools are shown - for example GEGL operation and colour tools are omitted. All tools can also be accessed by opening the "Tools" menu. To switch the window to toolbox, you can use Ctrl + B. Shortcuts written here are the default values - you can change them any time in "Edit > Keyboard Shortcuts" or "Edit > Preferences > Keyboard Shortcuts".
More sophisticated tools are not in the toolbox, but next to the Tools, in the Filters menu.

Tool options
thumb|right|10000px
By default, activating any tool will have the effect of showing its options under the toolbox. Each tool has its own set of settings and any changes to them are kept through the current session. There are also four buttons under any options.
File:GIMP-Toolbox-ToolOptions-SaveOptions-Icon.png Save options to... - save options of the current tool
File:GIMP-Toolbox-ToolOptions-RestoreOptions-Icon.png Restore options from... - restore options from saved file
File:GIMP-Toolbox-ToolOptions-DeleteOptions-Icon.png Delete saved options... - delete saved options
File:GIMP-Toolbox-ToolOptions-ResetOptions-Icon.png Reset to default values - reset them to standard.
You can hide them by clicking on the arrow next to the tool name and deselecting Show Button Bar. You can also access these from the same menu under Tool Options Menu.
Colour, Indicator and Active Image area
thumb|right|10000px|Colour, Indicator and Active Image areas respectively.
Below the toolbox can be placed these three areas. This is set in "Edit > Preferences > Toolbox" and any of the three can be placed there.
Colour area
Shows current foreground and background colour. Clicking on either will bring the colour editor dialogue.
Clicking on the symbol in the lower left corner resets the colour to their defaults. The D key has the same effect.
Clicking on the symbol in the upper right corner swaps the foreground and background colours. The X key has the same effect.
Indicator area
Shows currently selected brush, pattern or gradient. Clicking on any of these allows to change it.
Active Image area
Displays a thumbnail of the active image. Clicking on it will bring the Images dialogue up, allowing you to select an image.
