Better organisation of movies


I wonder if there is a way / custom firmware / missing setting… of filing movies. 

What i would like to see is a system where you can click action, drama, thriller and all the movies that have these 3 tags are shown to browse. i understand that there will be quite a lot of data to change in the files metadata, but i just wonder if this kind of system already exists. 

i currently have nested folders something chronic, and its pretty annoying!


Custom Firmware is available in the Internet (Not supported), but I do not know if it provides the features you are describing.
