Add parameter to EXTF
- 
 My suggestion is to add a parameter to automatically enter the date and time directly from the phone to a file when entering data.

 Hello! You mean like a boolean flag to enable / disable date time prepending to each line in a file. For example: [date_time] text [date_time] text2 ...when flag is enabled and text text2 ...when flag is disabled? Can you confirm this? Thanks.
