JimRac: On those two features, I can say that they are definitely both coming with Scrivener 3 for Windows. I am not sure on their status for the initial beta, though.
I know the Windows team had hell getting outliner sorting working, because apparently it’s not like with the Mac frameworks, where I just sort the data set, but more complicated somehow using Qt. So right now I’m not sure if the bugs have been ironed out enough for it to appear in the initial beta or whether it will be introduced in a later beta.
True Scrivenings mode is a necessity for getting Page View working - Scrivenings needs to happen at the model layer rather than the view layer so that the composite text model can be placed in any type of view (a page view, which consists of multiple text boxes or a single view). This is another feature that has caused the Windows team a lot of grief with Qt. I believe they have it all working, but the last time I checked, there were still bugs, so I’m not sure if they will also hold that back for a later beta once the bigger bugs are fixed.
Funnily enough, I don’t think any other apps offer anything like a true Scrivenings mode (StoryMill on macOS maybe?). All other apps I’ve seen that have added something like Scrivenings mode in the past few years do it the same way our Windows team had to do it - multiple text boxes. (Perhaps not surprising: getting the Scrivenings model layer working on macOS probably took two months of work in itself - fortunately back then I didn’t have anyone waiting on me for the feature.)
So, these are definitely coming but you might have to be patient beyond the first beta.
All the best,
Keith
