well this is it... in movable type you have the possibility to create new index files and rename them as you like past the code and give that files an output, the directory that you want them to be.
and i thought, why not have a plugin that do the same in wordpress???
so i asked a developer friend of mine if this could be done for wordpress!
well, here it is the answer:
A manager for files, you can copy, move or delete existing files between themes - only for wordpress 1.5
hope you like it.
