There is no change in the RSI functionality. The idea is that everybody can adjust the oversold and overbought regions shown in the RSI indicator. So if you like to change these bands then you can do it here.
Important: Original Code is written by JusttyMaldonado and TradingView itself. I simply added the functionality to adjust the bands to the values you like. It seemed helpful to me as I sometimes changes these areas so it might be helpful for other too.

Just saw that the title of the line surrounding the oversold and overbought regions are not correctly named in the settings. Corrected that with this update.
