Thank you!
Ah, “marked as they come in” means the testing will take a while…
I updated code, but did not re-create folders, in case it makes any difference. I have folder _filtering_test, and under that topic1_filters and Topic2, in which I have a bunch of feeds. While in topic1_filters I’ve added a couple folder rules, and when viewing Intelligence Trainer they do show up under _filtering_test - topic1_filters. Then I went to Topic2 (which has some of same feeds), and tried adding some rules there - and currently they show up in Intelligence Trainer as belonging to _filtering_test - topic1_filters. So currently saving works, but it seems there may be an issue with assigning them to proper place, especially when some duplication is in place.
