Added a marker on the title bar ☑
Added 2023-02-06 21:00:42 +0000 UTCPreviously, the downloader would display a ✓ mark on the page title when the download was complete.
Now the downloader adds a ☑ mark, if you see ☑, it means that the completed download task is not created from the current page. This avoids confusion at some point.
It replaces ✓ when:
1. When the download is complete, the URL of the page has changed from when the crawl started.
2. After the download is complete, if the user changes the page number of the current page (that is, flips the page), then ✓ will change to ☑.
