Do you know how many characters left?
In the Field «Single Line Text» and «Paragraph» can be the maximum length of value be set. The characters must be limited, especially when it goes to other systems.
In Paragraph, when you add your information you don't know how many characters you have used.
As example, if it is limited to 1000 characters, it would be very helpful to have a counter that display the length of your actual text. If you have used up the maximum of characters while writing, it would be helpful to know this in advance.
How it could be solved is shown in the pictrue.
