[kranthivakati]

Actually in the theme section there are four options i.e Default(System) ,black ,Dark , White
here we can remove black option's because there is no use of black any ways we can have System ,dark ,white mode to access the application.

yes because the alignment are not good as expected please check and let me know and at-least need boarder when using in black mode
