The fact that it is an open source project makes me feel more comfortable using than other software out there, which are only available as proprietary solutions or require you to pay for them.
I have not found anything so far that would be worth mentioning specifically but overall its great! It does what we need at this time - create content easily without having to install too many modules etc., nothing really comes to mind right now. We're working mainly from mobile devices (iOS / Android), so we don't use any desktop applications very often.
