For example, after down-scaling an image, sharpen of 20% can work well.
Unsharp tends to introduce artifacts if overdone.
After scanning a greyscale engraving I sometimes do a gaussian blur
followed by a sharpen at 80% or so. THis works better than
colours->threshold if you're going to scale down the image.

Which one are you using? It's not so much the goal to reduce the
number of plugins as to get rid of bad ones and replace them
with better ones..
