GFM is simple tool meant to automatically reduce number of filter in Gmail and get rid of duplicated filter. It compares each filter without its from field, gets rid off duplicates and concatenate corresponding from fields into single filter so it works as before. Tool works best if user creates many simple filters in Gmail e.g. from + label. In my case it reduced n. of filter from 160 to 80.
