Make fast mode the default mode and remove prompt #401
Looks like we haven't got any major negative feedback during the opt-in period of the fast mode (more info here), and the performance results are extremely positive from people opting in: between 5X and 15X faster depending on the project size:
Based on that, we've decided to make the fast mode the default mode on fuzzy finder and remove the opt-in prompt. We're going to leave the config options to allow user to revert to the old behaviour for a while, just to get some time for some potential obscure edge cases to pop out.
I'm planning to release a new version of the fuzzy finder once this PR gets merged and cherry pick the new version into the Atom v1.39 release
