I would like to see an option to click into the left gray column where the line count resides, and be able to make some sort of tick mark there to easily reference that line location later. I believe this would come in handy in many instances.
We felt the same. 
That’s why there is already a feature for this called Text Bookmarks, and they work no matter if you have the ruler on or not. See §14.12 of the PDF, pg. 147.
I see that now. Yes, it works, thank you for giving me the page number in the manual. I missed that.
But the bookmarks indents the text one space. In my mind, I had envisioned the bookmarks standing to the left of the text, where it doesn’t interfere with the flow of the words. In addition, is there a way to show a list of all of the bookmarks in that document? I wasn’t able to find such a thing. My initial impression was, as I mentioned, that the bookmark would be preferable if it were to the left of the text where it wouldn’t cause the next word to be moved right one space.
That wouldn’t really be possible since the text box is a fixed thing and these bookmarks are for all intents and purposes, just special and easily applicable inline annotations. There is nothing terribly out of the ordinary about them, so even if it was easy to get text to escape the text boundary itself, it would be difficult to reliably offset these things dynamically. It’s academic anyway as this isn’t something text can do.
There are advantages to having them in the text, just as there are advantages to inline annotations. For bookmarks, you can easily strip them all out when you are done with a simple search and replace for [* ]; You can search for them with the Find by Formatting feature across the entire project; they can be typed in by hand if desired; they can be custom titled by adding text within the blue area; they can have “header” style bookmarks with a double-asterisk that can be used to organise lots of them into sections; et cetera.
To get a list of all bookmarks in the active text view (works across scrivenings), click the icon in the header bar and access the Bookmarks menu. This menu is also available in the main View menu. The menu uses any custom titles that have been applied. If none exist, the first line of text following it will be used.
On the preservation of word flow: well, I’m not the best person to talk to on that score because my scrivenings look like an explosion of highlighter markings, inline annotations, and other Disturbances. I see the editor as a drafting board that produces text, and don’t at all see it as a perfect mirror of what the book will look like. That looks nothing like what I see in Scrivener. So, yeah, like I say I’m a bit out of touch with your concern. What I would say is that breaking flow is in my opinion a good thing for a bookmark to do. You want to see it. You want to engage with it and be reminded by it. If it’s hidden half of the time by a non-visible ruler, it isn’t a burr that is constantly reminding me to “fix this” or whatever the case may be. But that is all a matter of preference.
OK, Thanks for explanation.
Just another thought, if the indent really disturbs you, you could try using inspector comments for the same basic effect. They act as bookmarks, all showing up together in the inspector pane and allowing you to jump to that section of the text when you click the note, and you could just type a title or the line number or whatever there so you know where it links. It will make a box around whatever word you choose for the link, but it won’t indent or anything and you could use white as your note color to make it a little less stand-outish if that’s your preference.
Oh, bother. I’m not going to cave so easily as I thought. I still think that an ability to place a tick mark, even a simple black mark, beside, or overlaying a line number, would be a helpful addition. It doesn’t matter whether it can be easily done or not, or whether it cannot be done at all. It would still be nice to have. And I’m stickin’ to it. But, I appreciate the difficulty or impossibility of it being practically implemented.
Hi,
Just to give the official development word: Sorry, no plans for this.
All the best,
