Hi Adam! I like your suggestions. Comedy / humour is something we should have, I think, and Steampunk is hot at the moment.
We will look into this, but can't promise that we get this done - adding tags retroactively into our database is a huge amount of work. If we decide to add these tags, in the beginning they will only be added to the new books.
I've just add a new novel called Martial God Asura witch is part of a growing Genre xianxia(growing in America really big in China).
I think adding tags for Wuxia and xianxia would be a good idea since a lot of those novel where licensed and are being sold on Amazon .
Xianxia is a type of Chinese Martial Arts novel genre developed from the Wuxia genre that is heavily influenced by Taoism and Buddhism. It was first introduced in the Republic of China and became popular worldwide in the 21st century.
Wuxia which literally means "martial heroes", is a genre of Chinese fiction concerning the adventures of martial artists in ancient China
