ChannelSort per ChannelSortDev

YouTube's channel pages only let you sort by Latest or Popular (all-time).
ChannelSort adds a third option: Popular within a time range you pick.

Ever want to check what a channel's best video was last month, without
scrolling through everything they've ever posted? ChannelSort adds a
"ChannelSort" option right next to Latest, Popular, and Oldest on any
channel's Videos tab. Pick Last Week, Last Month, Last Year, a specific
month, a specific year, or a fully custom date range, and see that
channel's top videos by view count for exactly that window.

FEATURES
- Adds a native-feeling sort option directly to YouTube's own sort bar
- Quick presets: Last Week, Last Month, Last Year
- Hover Last Month or Last Year to jump straight to a specific month or year
- Fully custom date ranges
- Results shown in a clean, large grid so thumbnails are easy to browse
- Uses YouTube's official Data API — accurate view counts and dates

SETUP
ChannelSort uses the official YouTube Data API v3, which requires a free
API key from Google. A step-by-step guided setup (with screenshots) opens
automatically the first time you install the extension, and can be
reopened anytime from the extension's right-click menu. Typical setup
takes about five minutes and Google's free tier covers well over 1,000
sorts a day for personal use.

PRIVACY
Your API key is stored in your own Chrome sync storage and is never sent
to us or to any server we operate. ChannelSort talks directly to Google's
API using your own key. Full privacy policy: https://channelsort2.github.io/ChannelSort/

ChannelSort is free and independently made. If you find it useful, an
optional donation link is available in the setup page and in the
extension's right-click menu, never required.
