Add direct export to Citavi

Many/most journals release special issues dedicated to specific topics. It would be valuable to be able to mark a whole issue as a favourite, so that I can easily return again and again until I've read or saved all articles of interest (particularly useful for those weekly journals, where it is easy to get behind). I was thinking that enabling a change of colour in the list of issues would be one way of handling this, or enabling the addition of an icon to the list of available issues, but there are probably other/better ideas.

Provide a means of sharing a link to an issue.

Currently, BrowZine makes it very easy to share individual articles, but in the iPad app, I can't currently see a way to share a link to a whole issue (apologies if I've missed this). This would support a range of a library's current awareness services.

For example, if only two shelves were displayed, then the journal cover images could be enlarged to fill the space.
