[soumikbaithalu]

@codingninja11 okay, you can work on an issue or one request don't go for darker black instead go for a black-grey theme color which looks like this also, do a little animated if the user click the button animated do some creative, no pressure if you can't do just simply add button okay enjoy !!! 😄
