Dear Manuscripts Team,
This product has potential. But it is failing at the basics miserably.
As a manuscript preparation software, I would expect referencing to be sorted. Especially your history with Papers. But papers does not work in the app environment! I cannot get it to format my references properly. This is a deal breaker right at the outset.
Fullscreen does not work when trying to access the panels. This is important to allow the minimalistic approach you are looking for.
There is a host of other problems but i'll let others relay them to you.
Deleting the app as it is useless for my current deadlines. I have wasted quite some time with this and won't be back until it clearly has some improvement!
