* Folder watching will now appropriately ignore changes that occur in blacklisted folders. * Fixed up recently updated from dashboard not opening a pre-sorted page. There were issues with how encoding and decoding was done plus missing code. * Fixed up all streams from Dashboard opening to correctly filtered pages. * All search linking now works. * Rating tooltip and stars are bigger on mobile. * A bit of cleanup * Added day breakdown to user stats page. * Removed Token checks before we write events to the history table for scrobbling. Refactored so series holds will prevent writing events for reviews, ratings, etc. * Fixed a potential bug where series name could be taken from a chapter that isn't the first ordered (very unlikely) for epubs. Fixed a bug where Volume 1.5 could be selected for series-level metadata over Volume 1. * Optimized the license check code so that users without any license entered would still take advantage of the cache layer. * Sped up an API that checks if the library allows scrobbling * Cleaned up the mobile CSS a bit for filters.
