Fantasy Sync Assistant helps fantasy baseball commissioners maintain a clone league on Fantrax that mirrors their ESPN league. It reads the ESPN Recent Activity page, indexes all add, drop, and add/drop transactions for any team, then automates the Fantrax Commissioner Claim/Drop page to apply those same moves.

Key features:

• Scrapes all transactions from one or more ESPN Recent Activity pages (navigate each page and the extension collects them all)
• Displays the full indexed transaction queue in the extension popup, color-coded by type (add in green, drop in red) with oldest-first processing
• Cutoff date/time filter (YYYY-MM-DD HH:MM) so previously synced transactions are skipped, while also supporting pasting ESPN-format timestamps like "Mon Apr 6 6:19 am" which are auto-converted
• Press F8 (or the popup's Next button) on the Fantrax Claim/Drop page to process the next transaction: auto-selects the team, fills the claim search box, highlights the player to drop, and clicks Submit
• A confirmation dialog appears after each submission for review before moving on one-at-a-time and manually confirmed

Designed for personal use by a commissioner who manages a private clone league.
