The latest months I’ve been working as an employee with Quanta on Xubuntu, and I love the way snippets is handled in Quanta Plus. They are stored as simple .txt-files, which are created when you drag selected code into the sidebar. The snippets are called “Templates”, which might be a little confusing. They also have a scope – Global, Local or Project. I mainly use Global, so I have all in the same place and can reach them. I then share the with Dropbox, making the snippets available in my OS X and Windows too.
