• Device: Lenovo Tab4 8 plus

Issue

Night mode option doesn't work as intended for File browser, it's solely dependent on Reader's Night mode.

Steps to reproduce

1. Open KOReader i.e. view File browser
2. Change Night mode option
3. Close & reopen the KOReader > The previous change is not saved
4. Now if you open Reader & follow step 2,3 then after the restart File browser theme changes.

The easiest way to reproduce is: suppose I want to use opposite theme for FM & Reader then with current implementation I can't do it.
Also

1. Open KOReader i.e. view File browser
2. Change Night mode option
3. Open any book to view Reader
4. Close & reopen the app > Now File browser theme shows correct theme

Conclusion : File Browser theme is dependent on Reader i.e. FM theme changes work if you atleast open the Reader or simply change theme from Reader...while both FM & Reader theme settings should be independent to each other.
