 Changing the Plex URL takes effect on your next page load — refresh your Plex tab after saving a new one. Toggle and delay changes apply immediately, no refresh needed.
 
+Clicking **Save** closes the popup automatically shortly after confirming the save, so you don't have to click elsewhere to dismiss it. If something's wrong with what you entered (like a blank or invalid custom URL), the popup shows an error and stays open instead.

 ## How it works
 
 The extension's content script runs on every page but only activates once the page's hostname matches your configured Plex URL. From there it uses a `MutationObserver` to watch the page for any `<button>` or `[role="button"]` element whose visible text contains "skip intro" or "skip credit" (case-insensitive, so it still matches if Plex appends a countdown like "Skip Intro 0:05"). When a match appears and is actually visible, it schedules a click — immediately if its delay is 0, or after the configured delay otherwise. Right before a delayed click actually fires, it re-checks that the button is still present, visible, still says "Skip Intro"/"Skip Credits", and that its toggle is still on — so turning a toggle off, or Plex removing the button, cancels a pending click instead of firing it late. A short cooldown per element stops a single button from being double-clicked in one burst, but still allows a later click if Plex reuses the same button element for the next episode.

-The suite covers: clicking Skip Intro/Skip Credits, ignoring non-Plex pages, respecting the on/off toggles, matching a custom server URL, reacting to buttons added dynamically after page load, ignoring unrelated buttons, handling countdown suffixes in the button text, not clicking hidden buttons, correctly re-clicking a reused button after its cooldown, delayed clicks (including cancellation when a toggle turns off or the button disappears mid-delay), and the settings popup's save/validation/load behavior for both the URL and the delay sliders.
