cfg_locate_cfg_file means that to open a document with an association, ndless has to (very slowly) trawl through the entire filesystem. This adds a delay of 10-15 seconds on my calculator with a pretty full internal filesystem. I'm not clear on why it has to search the entire filesystem for a file that's supposed to be in a specific place. If it's for compatibility with Hide Manager, maybe there should be an API for changing the ndless folder location. At the minimum, can we cache the location after finding it the first time? I'm willing to implement any of these changes, but I want to understand why it's the way it is now before I start changing things.
