Usability Improvement 2 Rated 2 out of 5 stars
Agree with previous post on usability improvement: lacking direct file attachments is a BIG gap in Lightning. The solution proposed by the author (Filelink) is not feasible, at least not in my environment.
The other gap: there is no indication on the GUI whether an invitee has accepted, declined or tentativly accepted a meeting.
Sorry about not being able to directly attach files. If we just allow this now there will be massive performance issues and more complaints than thanks. Filelink is just a workaround, maybe just give it a try!
