They are doing work on the UX, but that's work for a different kind of people than the folks who do security. Security is an enormous concern with an office suite. The formats which need to be supported by an office suite are terrifyingly complex, and people open documents from untrusted sources on a regular basis. Opening malicious documents in office suites is a major vector for malware attacks, especially in the "commercial world". and as soperj points out, LibreOffice often has better interop with word, especially older documents. It also correctly opens and saves ODF formats, generates better quality PDFs. The UX is also kinda hard to objectively iterate on. The current iteration of the office ribbon generates some amount of positive feedback for new users, but experienced MSO and OO.o users often prefer the current style of LibreOffice. If iterating on the UX means anything, it probably means adding a second UI. Outside of UI, it would probably be good to get better cloud (or even collaborative) support. It's frankly not certain how that would be done, maybe federated synchronization servers.
