Guide scheme

Different color scheme - Red is usually associated with record - can we have that instead of that murky green brown ?
Also when highlighted in guide all programmes are white whether set to record or not - can this be changed so easier to differentiate?
Also can a symbol be added to differentiate season pass from single record ?
Also even if we can’t have PIP can the buffer be retained so you can view the guide and set another programme to record and then continue with viewing ?
