Creates a new layer with a grid, rotated 45 degrees, to help you choose corners for cropping.
Move the grid until a line intersects a feature in your image, then crop so that the grid line meets a corner of your cropping rectangle. You can then use the grid to choose the opposite corner, but make sure you don't change either of the sides of your original corner.

Creates two new layers: one containing the Luminance, and the other the Chroma information in the form of a Grain Merge. Optionally, it will color-enhance (maximize saturation in) the Chroma layer while still keeping it luminance-neutral.
This allows you to do noise-reduction and sharpening on the two layers separately.
FX-Foundry/Photo/Enhancement/Maximize Local Contrast...
Like Stretch Contrast, but instead of using the minimum and maximum pixel values from the entire image, uses the minimum and maximum in the vicinity of a pixel to compute its new value. Takes a while to run, but really brings out textures. Result is a Grain Merge layer that adjusts values of the original image.
This filter operates on the visible image, not on a layer or selection.
This is a very simple script that adds the rule of thirds guides to the current image.
I used to add guide by guide by percent, then crop, remove the guides and add them again one by one. After many times I did it like that, I decided to create a script to do it faster, for which I had to self train on how to do it using script-fu, to avoid poor portability.
I created the script with my Fedora 8 Linux distribution for GIMP 2.4, but it also works for 2.6.
This script works for any platform that GIMP works with.
This is to use if you have Anime Studio (v5), and want to convert your layered image into an character on that program. The script works on GIMP 2.4.2 and Anime Studio 5, and that's all I've tried it on. Each layer is saved as a 24-bit PNG, using each layer's name as a base, and referenced in the output ANME file. You can choose the output folder for both the ANME file and the image files. You can also rename the ANME file to something besides the base image name, but if unspecified, the ANME's name is the same as the image name, minus the extension.
