Improvements for Browsing Journal Content Implemented

We have implemented several minor changes to support users browsing and discovering content on www.mdpi.com. Readers will notice new buttons on the right and left side of each article and issue page. These buttons facilitate navigation through an issue or volume. Related articles from our journals and other publishers are displayed on the abstract page of our Web of Science and PubMed covered journals. Further, keywords on article pages are now linked for a convenient search across all MDPI journals.
