2026-03-08 — Version 1.2

Fixed script initialization on pages with many elements

Rewrapped all JavaScript in an IIFE to prevent conflicts with other plugins and avoid top-level code running before document.body exists
Fixed crash caused by createSvgBackground() and ResizeObserver executing during script parse when DOM was not yet ready
Replaced window.onload assignment with a proper DOMContentLoaded listener pattern to ensure the script initializes reliably regardless of when it is loaded by the browser

New post meta field _nxt_timeline_selector allows overriding the global target selector on a per-page basis
Override is editable directly in the Gutenberg Document Settings sidebar under "Timeline Selector"
Global selector (configured in Settings → Animated Timeline) is used as fallback when the field is empty

Frontend script version now uses filemtime() instead of the hardcoded '1.0' string, ensuring browsers always load the latest version after an update

it is now possible to apply effects when scrolling past a timeline stop (e.g. change its color to black and white)
scroll effects can be inverted, so it's possible to first apply a custom filter and then remove it when scrolling past the respective item
upload for custom .svg files now uses WordPress media library instead of the previous hacky solution
renamed timeline.js to nxt-timeline.js to avoid naming conflicts with other plugins

You no longer have to choose between a circle, a rectangle or no item for a timeline stop, you can now upload your own custom svg file
Option to set the width of the uploaded .svg file to properly customize the look of the timeline
Moved all inline JS for the WordPress admin options page to a dedicated file (/js/nxt-timeline-admin.js) to clean up the code (a little)
Improved UI as options that are not in use (e.g. color of timeline stop when a custom .svg is in use) will now appear greyed out / disabled
