Subject of the issue

In 2 lines LCD, when you are selecting a MNU_INPUT label (usually writen as (Label) on screen), it should be nice to append a preview of the value. This would speed up the review of the values. Otherwise we shall clic on the selected input label to see its value (and modify it). If we just want to navigate in the values, it is long and penible...

For example, the menus are:

MAIN MENU
SubMenu1

• Item1: value = 10 (integer between 0 and 100)
• Item2: value = "Apricot" (from a list)
• Item3...

At present when selecting SubMenu1 from the main menu, you see:
(Item1), (Item2) etc. on the second line, you don't see their values
It is only when you click on (Item1) you can then see its value and modify it

The idea is to print:
(Item1) = 10 then (Item2) = Apricot etc. on the second line
When you click on each (Item) you can then modify its value
