Item View for Tiwtcasting is a free Chrome extension developed by キィー. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This extension provides a means of tracking gift items received during a Twitcasting live broadcast.

When the extension icon is clicked, it opens the Twitcasting's broadcastertool page. With this extension, the host of the live stream can easily monitor the flow of gift-items sent by the live stream viewers. The extension offers a simplified version of the page, allowing for a more streamlined experience.

The visibility of various page components, such as the subtitle editor box or the category selector, can be easily controlled through check boxes in the option page or the popup window. If the user wishes to view the original broadcastertool page, they can simply disable the extension in the browser's extension management page and refresh the broadcastertool page.

Please note that this extension is specifically designed for the host of a Twitcasting live stream and requires the user to log in to the host's Twitcasting account.
