I know I can use advanced search/genre search/advanced options, and just click on the desired or undesired genres to include or exclude with the red and green icons... but no such feature exists (as far as I can see) on the main homepage of batoto or the [Recently added Comics] column to the right.
I like finding new or random things to read in the Latest Updates/homepage, but genres are unable to be filtered out--everything that's updated is shown there. It'd be great if some filter or blacklist feature is implemented (ideally site-wide, or in user profiles) so we never have to see or click on a title only to find out it's an undesired genre, i.e Tragedy or Yaoi.
