Hi, I looked but could not find the answer to this question in the manual:
Some icons appear with the corner page bent, and then some appear horizontally with red and blue stripes going through them…could you point me in the direction of some key that can tell me what these various variations mean.
There isn’t a grand key that describes all of the various icons in one place. That’s not a bad idea, I’ve added a stub to the binder chapter for this. They are described, but the descriptions are scattered about in relation to the features they associate with. Briefly: dog-eared icons mean that item has at least one snapshot. The “sideways” icon you describe is in fact a depiction of an index card. That means the item has a synopsis, but not main text material. The typed page icon means it has text material, and it always overrides the synopsis icon. The blank page icon means the item has neither main text nor synopsis supplied to it. So these icons are a useful “three stage” status indicator of your progress in fleshing out an outline, if you wish to use it as such.
There is not an icon for that. The problem is notes are decidedly “meta” and so you wouldn’t want to have it change the base icon, it would have to be a badge, and the badge space is already reserved for other potential indicators. We do have something on the list of things to think about which could help with this, but it will probably take place in one of the views (like outliner) rather than in the binder, so as to make it so that the feature can do more than just one thing with the extra space available.
Meanwhile, when the inspector is open, each of the little buttons at the bottom will acquire an asterisk if it has content. So you can pretty easily just leave that open and flip rapidly through a bunch of items with the down arrow on your keyboard to check for notes or anything else in the inspector. I often just leave the inspector open all of time when planning. I use too many of those things over there to open and close it, so I rarely lose touch with what has what.
Another thing to consider, if the document exists solely for its notes, is to move the notes into the main text area. In the inspector you can turn off “Include in Compile” and that will ensure it remains out of bounds for any final output. I like to use a special icon for items like this. Documents/Change Icon/Notes/Yellow Notes for instance. Once you assign an icon like that, it will be added to the recent list for easier access in the future. A tip, you can create a document template for note files like this, with the icon already set and the include in compile flag off. See §8.4 (pg. 75) of the user manual for details.
