Make the UI better

[kerk12]

The UI currently has a lot of rough edges. They need to be polished and the UI needs to be made more clean and elegant.

@kerk12 I have enhanced UI please check the PR. I have also added User change button. I have updated the splash screen button too.

@kerk12 let me know the changes in the PR and have a look over the PR too.

@DHRUVA-N-L-CHOUDHARY Please check my comment. Your PR is good, it just fails to build.
