Edit status bar

Create an app that has an option to edit the status bar. I have been waiting for years to see an app to remove the battery icon from the status bar, I just want to see only the percentage, so that I get enough space to see all notifications and a clean status bar. If someone know any app that works as said, please tell me.

Second thing is make the home screen edge to sharp corners, like the square edge that we have in the old phones. Now a days all the screen edges are set to oval. I have the Samsung A50 and I have set camera cut to hidden but still the home screen edge is having the oval shape.
