It would be nice if there was a way to filter out novels which have gone premium when searching. Having a badge/something on the novel to say that it's gone premium could also be useful.
A lot of people (including me) are looking for new things to read but don't want to start something only to find out that only 1/3rd of the chapters can be read for free without SS.
Being able to spot the premium novels from the search/browse page (without having to go into them and check the tables of contents) or filter them out entirely would make finding stuff to read much easier.
