yes, but first script is interesting because you can make visible automatically the first, third, fifth, seventh, ninth layers hiding the others layers or vice versa (second,fourth, sixth, eighth, tenth..etc), with second script you can change align pixel, see image...

These scripts works only on gimp 2.2.
sorry for my english.
With the first script your can make all layers visible (save the active one) or invert the visibility of layers, but you can't from a stack of all visible layers, show only every other one. At some point you have to manually select every other layer yourself. Surprising it doesn't work in 2.8. But just a SMOP in Python (the longest bit is the registration, the rest is mostly one-liners). A good project for someone who want to start coding python scripts

Adding an entry to select every other layer is left as an exercise.
Nothing in the second script that cannot be done with guides, the align tool, and moving a layer pixel by pixel using the cursor keys.
