A cool feature would be - to prominently display the Current Heading you are reading:
For example:
You are reading a section with the Heading “New Ideas”:
This would tell you, at all times, what section you are reading (so you don’t get lost in a sea of text.)
[Note: I searched, and found no solution for this]
I definitely agree. Here is a very similar feature request: Outliner sync with note while scrolling
It asks for the Outline item heading to be in bold rather than highlighted, but is otherwise right in line with this request.
Thanks.
Yes, that would be a good solution (highlighting the currently viewed Heading in outliner).
Last night, I made a very basic “Header Display” (with javascript):
Here is a screenshot (a note called ‘Coder’, a Header called ‘Past Code Challenges’):
The code is below (in the next post).
It works well for notes with long sections (such as book chapters).
It’s still rudimentary and unpolished.
What it does:
checks whether a long-section’s Header has scrolled above 30% to the viewport-top (and also checks the area above the viewport).
performs that check every 1000ms.
automatically stops that check when Obsidian is unfocused (if you switch applications), and resumes when Obsidian is refocused.
A Needed Improvement:
It works when scrolling Down a document, but does NOT work when scrolling Up a document.
This is because Obsidian uses a “dynamic DOM” to render only the CodeMirror-lines which are in the viewport and just above and below it.
That means - if you scroll Upwards into a long section, the upstream Header will not yet be loaded in the DOM (so there is no way to reach up and ‘grab’ it (until it’s almost in view)).
This can be observed in dev-tools, in the div called “CodeMirror-sizer”, specifically its first child, whose “top” property changes as you scroll up and down (thus dynamically loading/unloading the CodeMirror-lines of a long Note).
QUESTION: Is there a known method for ‘targeting’ elements which are above / below the dynamic-DOM?
That pastebin link expired, so I’ll post the javascript code for the basic Header Display here:
// HEADER DISPLAY 1.0
let docTitle = document.getElementsByClassName("view-header-title")[0];
//create Header Display box
let hDisplay = document.createElement("span");
hDisplay.className = "hDisplay";
let look = window.innerHeight * 0.3;
// console.log(look);
let prevTitle = "";
// start the check if obsidian is in focus
window.addEventListener("focus", function (event) {
console.log("has focus");
const timeBoss = setInterval(titleCheck, 1000);
// get last header in rendered DOM, get scroll position relative to viewport
function titleCheck() {
let hTarget = document.querySelectorAll(".cm-header-1");
let len = hTarget.length;
let lastTarget = len < 1 ? "" : hTarget[len - 1];
const { top: t } = lastTarget.getBoundingClientRect();
console.log(t);
let hTitle = lastTarget.innerHTML;
console.log(hTitle);
// if it's a new header, and it's above 30% from top of viewport, update Header Display
if (
hTitle &&
typeof hTitle !== "undefined" &&
hTitle !== prevTitle &&
t < look
) {
prevTitle = hTitle;
console.log(prevTitle);
hDisplay.innerHTML = " - " + hTitle + " - ";
docTitle.appendChild(hDisplay);
}
}
// stop the check if Obsidian is unfocused
window.addEventListener("blur", function (event) {
console.log("lost focus");
clearInterval(timeBoss);
});
});
I used the “JavaScript Init” plugin to add it to Obsidian.
“Highlight” is covered by this older request: Core Outline Plugin: highlight location of cursor/view
Arguably this thread could be merged into that one (and maybe someone else will do that) but for now I guess the “sticky” part of the request is distinct enough.
I use Sticky Headings - Obsidian Plugin and has been working as expected.
In the past I used Another Sticky Headings - Obsidian Plugin , but had some conflicts.
Still supporting the request, this is something that when missing is very noticeable.
I removed “(or highlight it in the outline)” from the title because there is a separate request for it and that feature has been implemented. Core Outline Plugin: highlight location of cursor/view - #62 by WhiteNoise
