Change video playback speed by simply scrolling your mouse wheel over the video.
No need to open the player's speed menu.

■ Features
- Hover over the upper part of a video and scroll (up = faster, down = slower)
- Fine-grained control from 0.1x to 16x in 0.1 steps
- Pitch is preserved, so voices don't sound high-pitched when speeding up
- A clear on-video speed indicator (can be set to stay visible)
- The bottom quarter is excluded so it never fights with the seek bar

■ Works with Google Drive lecture videos
On Google Drive previews, the player lives inside a nested frame that is covered
by a transparent overlay, which is why many speed extensions silently fail there.
This extension bridges the wheel input across frames, so it works on
on-demand lectures and reference videos shared through Drive.

■ What it does not do
This extension only changes playback speed. It provides no video download
feature and does not circumvent DRM in any way.

■ Privacy
No browsing history, page content, or personal data is ever collected,
and the extension makes no network requests. It stores exactly one setting:
whether to keep the speed indicator visible.
