Most features from the previous Extra Features releases have been merged into the main Azahar branch. The only exception is the Secondary Screen Layout menu that allows you to select the layout and which screen to use from the quick menu - that feature is still in this version.
This version now includes two major features that are not yet merged into the main branch both of which are still very much in testing mode.
Desktop Build
Major overhaul of controller mapping and support that adds more clear names for controller buttons, controller hotkeys, and the ability to apply an input profile to all controllers (not just one).
Now also, if you try to map the same key twice (not including controller hotkeys) you will be prompted to clear the other map rather than failing.
Android build
complete overhaul of Settings that enables per-game settings and the ability to map gamepad axes to buttons and vice vera (and makes big internal changes as well).
NOTE: Both of these changes affect the config files, so if you use this release and then decide to go backward to the main release, you may encounter issues caused by config file changes. In the Android build, you will likely need to remove all of the controller configuration lines in the config file that represent controller mapping to re-enable gamepad support at all ("button_a=.." and so forth). The desktop build shouldn't totally break, but will require remapping when you go back. You may want to consider backing up your config file BEFORE launching this release, so you can simply restore that backup if you decide to return to the main branch. In an emergency, you can delete the config file(s) with no real data lost, just annoyances at having to redo your settings.
There's no guarantee these config files will continue to work even once these features appear in the main release, as we may make significant changes to this before merging. So back it up or be ready to start over!
