Who would have thought! Originally, the iffTeX was planned for a small group. What nobody expected was the enormous demand. Over time, many features have been added. First, an LDAP connection was developed. Then we implemented the track changes feature, a connection to ifflogin, templates, rich text mode, Git integration, Mendeley and Zotero integration and lastly a grammar checker. Now we’re happy to announce that it’s time again to introduce new features. Not only visually we are now close to the big brother “Overleaf”. Our service is now also equipped with a guest upload, files outline and a LaTeXdiff extension.
