Currently the buttons at the top of a series page are:
Subscribe, Bookmark Series, Edit Series, Delete Series, Reorder Series, Orphan Series, Remove Me As Author
Because subscribing and bookmarking are things one is less likely to want to do frequently, it would make more sense to use an ordering more like the Work buttons:
Add Chapter, Edit, Edit Tags, Bookmark, Comments, Share, Subscribe, Download
Moving "Edit Series" and "Delete Series" up would make them more salient, especially useful now that has gotten rid of the "Delete Series" button that used to lurk on the work posting form.
