I'd like to suggest to add a tag named "platonic relationships" to use for manga that are "focusing" [since platonic relationships are not really in the focus of the story but rather a side-element, focusing isn't a very good word to use, but the meaning should be clear with this statement xD] on relationships between 2 people below a certain level of intimacy (i.e. the characters share a special bound but don't have any physical relationship[i.e. no kissing,hugging,etc;holding hands is ok because it also is used between friends and relatives]).
I believe it would be good to differenciate platonic relationships and romantic relationships.
The main reason is that the focus of those two kinds of "romances" is generally different.
While normal "Romance" mangas mainly focus on how two characters meet, get attracted to each other and share a more or less physical relationship with each other throughout the story, those featuring a "platonic relationship" mainly focus on the interactions, thoughts and happenings of the two involved parties.
The story mainly revolves about how the interaction between the two parties change them and how they grow with each other and overcome certain obstacles rather than "how to confess", "how to kiss" or "how to get into their pants".
The other reason is that the Romance tag alone will/may mislead people looking for platonic love stories rather than "erotic" love stories and vice versa and promise them something they might not find inside the story, making them feel disappointed reading dozens of chapters for something that will never happen or drop the story disgusted if the cast is not so pure as the tag might suggest.
Good examples for stories that could get this tag would be Card Captor Sakura (Sakura & Shaolan) or Mamotte Shugogetten (Tasuke & Shaolin).
P.S.: It would also be good to add this since there is no differentiation yet for "straight" stories (homosexual relationships have, per definition on Batoto, a differentiation between more and less physical relationships via tags[Shounen/Shoujo Ai and Yuri/Yaoi] in addition to the smut tag, while romance doesn't have this yet).
