I have taken the plunge and currently work on a paper using manuscripts. I wanted to share my experience.
Overall I really like Manuscript's lean layout and enjoy opening the program more than I would using Word or Latex. I feel by now for me it's worth putting up with the remaining quirks, but I would still not recommend Manuscripts if you are on a deadline and require a very robust and finetuned program. What follows are a couple of observations:
- copy and paste is a lot more reliable than in 1.1.x versions, although still a little clunky/slow. There's no drag and drop of highlighted text passages.
- figures get heavily rasterized upon export, basically rendering the figure integration into a Manuscript file unfeasible for me. I store figures and figure legends in a separate Word file for now.
- the upcoming feature to export figures either separately or at the end of the manuscript will be very useful but does not yet work
- linking to figures rather than embedding would be very useful
- it is great to be able to move sections around using the outline view
- it's very hard to change a subsection to a section; additionally, insertion of sections and subsections often occurs at the wrong point in the manuscript
- annotating/highlighting text will be very useful
- alignment of figure legends: when justifying text the figure title stretches across the entire line; in general, I would prefer having control over whether the figure title takes up an extra line (as is the current behaviour) or whether the legend starts on the same line as the title
- it is somewhat clunky to introduce new sections into the text; most of the time pressing cmd+enter does not insert a new section but a new subsection; changing the subsection into a section is difficult, since this option is not present on the menu that can be invoked by clicking on the blue circle (it only offers to change intot subsection, which it already is) and dragging it to become a section in the outline is difficult to achieve
- an option to insert page breaks would be nice (e.g. for the title page)
- if you want to use Manuscripts be aware that currently there are no collaboration features and re-import of Word files into manuscripts is not ideal (loss of all metadata for citations); my workflow will be to export a Word file from Manuscripts and send it to collaborators, then manually insert modifications into the Manuscripts file rather than re-importing the Word file into Manuscripts.
Overall I think Manuscripts will be a great tool but is still not quite there to be recommended for the less adventurous user. I look forward to the promising announced features!
