As title says i want to see that feature badly.
For example i has 2 pretty complicated quick filters: one that specifies spot, like position, amount of raises occurred and such; another that specifies board texture and players' hand, once again consist of many small filters.
If i want to use them at the same time, i need to complement one with another and save it as separate quick filter, and that takes some time. And if i has more than 2 complicated quick filters i want to combine it becomes really messy.
From my perspective it is not really hard to add extra "quick filter" tabs into a software and make it so they work simultaneously. Hope for yours' cooperation, thanks.
