0.42-beta-1 is out now with the following:
Games can now be filtered by Platform, Genre, Developer, Publisher, Rating, Play Mode, Region, Series, Status, and/or Source fields
The default root filter can now be changed to any of the above filtering options (Options > Default Root Filter)
A default secondary filter option has also been added that will allow you to add a second filter to default navigation (Options > Default Secondary Filter); this will allow you to navigate by platform and then by genre, for example
Fully dynamic and nested filtering is now available, which means you can filter to anything at any time; long press on a platform or filter and select Filter, or choose Filter from the top menu of any games list
An All Games option has been added to all filter views
Added the ability to customize all platform/filter media; you can long press on a platform or filter and select Edit Media to change all media items
The Android games list will now only show apps that are in the Android Game category; unfortunately though, Android apps are often miscategorized, so it might not be perfect
The Arcade platform now supports the RetroArch Flycast core
The new dynamic/nested filters system is extremely effective, to the point where I'm wondering if we should actually do something similar on the desktop. Also thanks to @faeran for some beautiful new genre banners:
Remember that this is a beta release, so you'll need to check the box in Options to update to beta releases in order to use this version. We're hoping to get help from everyone in this thread to get rid of any bugs and get the official release out next week.
