About Book-clicker Companion

Book-clicker Companion adds features to Your Calendar, MarketPlace, Launch Center and Messages. The hot pink color indicates UI added by this extension. When you click and open a day on "Your Calendar", a "Review Ads" button is added to show a UI with more convenient ad info about other people's ads you send out in your emails. In the "MarketPlace" tab, "Est. Clicks" and "Ads" columns are added to help you better understand the value of booking with this list. "Book" buttons open in new tabs instead of the same tab and are color coded as follows: green=mention swaps recommended with this list based on size and click rate; yellow=you have pressed the "Book" button for this list before in this session (yellow buttons are cleared when tab is refreshed); red=all your titles have been booked with this list either in the future or the last 25 days; cyan=original color with no opinion on this list. Also in the "MarketPlace" tab, the "Scan" button is added to provide an alternative UI to pressing "Book" buttons. The "Best Lists" button is added to provide a UI that uses historical booking data to suggest lists that performed well for you or others in the past but you haven't booked with recently. The "Thank You" button on the "MarketPlace" tab interprets a "Bookclicker Promo Confirmation" email so you can easily see the email with the ad that was sent and start a new conversation or continue an existing conversation to send a message to thank the list owner. The "Refresh Bookings" button on the "MarketPlace" tab is used in conjunction with the "Fetch Bookings" button on the "Launch Center" tab (presumably in a separate browser tab) so you can synchronize historical booking data to the "MarketPlace" tab without clearing the yellow "Book" buttons. In the "Launch Center" tab, the "Fetch Bookings" is added to fetch the latest historical booking data for all your titles; "Launch Center" does not automatically do this. The "Download Bookings" button is added to download your own historical booking data for all titles (there is no reason to do this yet). The "Promo Calendar" button is added to provide a UI to show a calendar of emails going out with an ad for one of your titles from other lists so you can plan bookings. The "Messages" tab styles the UI of Inbox, Sent and Trash as well as individual the "conversations" themselves to be more readable and adds "note" sections to other lists for your convenience. In v0.1.5, "Best Lists" scoring bugs were fixed and "Ann" historical booking dataset was updated.
