Just an awesome add-on to have. Using Gmail since it's inception period. Never felt so liberated. Thanks for freeing us!
I also found someone commented on one of your youtube videos saying that a filter manager is used, I am looking for that too now.
Nonetheless, fantastic work. Please keep up the great work!
PS: Just realised someone said below s/he got the different sheet only. S/he has to go through the videos I guess from the website! That should clear up lot of confusions, if any, for the noobs!
