Is it legal to do the same as gmail for labelling items?
I have a question about copyrighting. I would like to develop a web application for document management. I like the way Gmail works for labelling mails (colorized labels & drag'n drop labels on items in a list). I'm wondering if I can apply a such functionnality on my web app? I repeat my web app is not a mail manager, it is a document manager.

Thank you in advance.
