Thanks for the kind words, as well as the constructive comments! We're always happy to hear from users, and we appreciate new feature requests.
Regarding the first request: I'm a little hesitant to go along with this one, as adding TinyMCE options would add a fair bit of clutter to the interface, and I think people are accustomed to not necessarily being able to edit title fields in that way. It's also something that might be best left until copyediting. That said, if you could possibly point to other web forms where titles are handled better; or perhaps if there are others who think this is a good idea, we could definitely consider adding it.
Regarding the second request: I've added this to bugzilla as a feature request here: http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=5882
. Please feel free to CC yourself to that report for future updates. And thanks again for the comments!
