The reading list shows the series title, number of chapters the user has read, and the number of chapters that have been uploaded so far. It would be helpful to also include the total number of chapters in the series, since that way you can tell at a glance whether a series is completed, and how far the translator still has to go. You can pull the data directly from the novel page by including "Status in COO". Release frequency would also be a helpful column.
Good point. Add it as an optional feature, so people can choose to add more columns only if they go into the settings.
