Chrono 3.0.1

A housekeeping release with no change you'll notice while watching.

• Chrono takes no donations. "Support Chrono" still opens a page where you can rate, star or share it, and the code now calls that link support, not tip.
• A new README, with screenshots, store links and an install table.

The Chrome Web Store and Firefox Add-ons stay on 3.0.0, which behaves the same. The zips below are for anyone building or reviewing from source.

Chrono 3.0.0

Chrono 3.0.0 is a ground-up rewrite. It fixes the old "times only show after a reload" bug (#2), and it now runs on Firefox as well as Chrome.

What's new

• Panel at the top of the sidebar, styled like the rest of the page: the watch time left at your speed, your finish time ("Ends 3:45 PM · at 1.5×"), and speed − / +.
• Speed table: remaining and finish time at every speed from 0.25× to 4×. Click a row to switch.
• Chapter scope and Playlist scope: time left in the current chapter, or up to any entry in a playlist.
• Targets: set "Done by 6 PM" or "I have 45 min", and Chrono works out the required speed and applies it in one click.
• Past 2×: + keeps going in 0.25× steps up to 4×.
• Player badge (optional): "/ ends 3:45 PM" after the player's time, fullscreen included.
• Playlist summary on playlist pages: total length, watch time at your speed, and how many entries are unavailable.
• Pauses during ad breaks, stays honest on live streams, and works in background tabs and across in-page navigation.
• Keyboard and screen-reader friendly, follows the page's light or dark theme, and respects reduced motion.

Privacy
