Usage

0. Backup all data on your device
1. Disable App List mode in EdXposed Manager (Maybe it's optional?)
2. Install this module
3. Go to EdXposed Manager - Modules and press "refresh" button (since BOOX OS does not allow EdXposed Manager to automatically take action after an app is installed/upgraded; you can enable "EdXposed Manager" module to make this mechanism work again)
4. Enable this module in EdXposed Manager
5. Create files in /data/local with root permission if you want to switch on/off some tweaks; See below
6. Reboot
7. Enjoy

Features

You need to install and enable the Show Navigation Bar Magisk module to enjoy (the navigation bar and) the tweaks in this Xposed module.

Also, you are advised to install SystemUI Tuner Redesigned to tune more things (per-app immersive mode etc.)

• Fix crash when tapping navigation bar buttons after enabling navigation bar
  (Default is enabled; to disable, create the file /data/local/xbtnf_disable_navbar_button_fix)

• Fix navigation bar color (make it transparent when in "Onyx Note" app; fix NavBar button colors in some apps) (Default is enabled; to disable, create the file /data/local/xbtnf_disable_navbar_color_tweak; if you want an always-dark NavBar, create the file /data/local/xbtnf_navbar_dark; if you want an always-light NavBar, create the file /data/local/xbtnf_navbar_light.)

• Fix the form of NavBar, switching the original "SwipeUpUI" NavBar to a normal form with back/home/recent buttons
  (Default is enabled; to disable, create the file /data/local/xbtnf_disable_navbar_form_fix)

• Change the layout of NavBar buttons with a layout string (Please decompile SystemUI.apk from the ROM and see in NavigationBarInflaterView class how your BOOX handles the string and generate the layout. Here's the source code just for reference)
  (Default is enabled, changing the layout to left[.5W],back[1WC];space[1W],home[1WC],space[1W];recent[1WC],right[.5W]; to change the layout string, create the file /data/local/xbtnf_navbar_layout, assign selinux context u:object_r:platform_app:s0 to it by setenforce 0 && chcon -v u:object_r:platform_app:s0 /data/local/xbtnf_navbar_layout; setenforce 1 and write the string into it. If you write nothing more than whitespaces, the fix is disabled, falling back to the default string back,home,left;space;right,recent which only shows a single "back" button for unknown reason)

• Make Alt+Tab able to bring up Overview (Recent Task Switcher)
  (Default is enabled; to disable, create the file /data/local/xbtnf_disable_alt_tab_overview_tweak)

• Allow changing the E-Ink optimization configuration for system (whitelisted) apps (Be careful!) (Default is enabled; to disable, create the file /data/local/xbtnf_disable_all_apps_eink_optimizable_tweak)
