As a scrivener user i am very excited to see manuscripts scaled down and clean interface. One problem with the split screen view in el capitan and manuscripts is that the manuscripts window gets very wide borders around the text. I basically get 1/5 of the screen for the text, the rest is dark grey border. I can´t seem to get it wider either.
The split screen and a widescreen monitor is extremely useful to me allowing excel/spss/papers for half the screen and word/scrivener/manuscripts in the other half.
Hopefully just a fairly simple to fix bug.
