30.01.26. CLZ Book Collector added reading history tracking

CLZ Books Web now features reading history tracking. It allows you to not only mark books as read but also track multiple reading sessions, enter both start and end dates and even track your reading progress, i.e., the number of pages read out of the total. You can also use folders to group by reader, reading status, year read, month read or reading date to get a good overview of which books you or someone else in your family is reading, finished or abandoned during each period. Your full reading history is displayed in a separate section on the book details panel, as well as in the new "Reading Statistics" section. The developers have also added intelligent automation settings for starting and ending a reading event. You can fine-tune what CLZ Books Web does when adding a new reading event or setting the status to "Completed." For example, you can allow the end date to be automatically populated when setting the status to "Completed."
