About Duplicate Tabs Closer

Duplicate Tabs Closer automatically detects and closes duplicate tabs across all open chrome browsers. For now, it closes the new duplicate tab and redirects to the previous duplicate tab. Features to be added: - "On duplicate tab detected" Optionality (do nothing, close new/old, close new/old + redirect) - Filters: hash, search, path URL components - Active Browser / All Browser duplicate detection - Hotkey to close all tabs - Blocklist (perhaps to compare same document side by side)
