Review for Filter Button by ccciolll
Rated 4 out of 5 stars
Seems to works fine on my computer, can also tell if many filters can be applied DIRECTLY on the message (do not tells the filters that could be applied after other filters have been applied, but it is probably too complex to program).
Usefull for calibrate properly my lot of filters
