Idea Summary
I would like to see the setting for Format Mask actually used for data entry instead of just bing used for validation of data. 

Use Case
This could be helpful for date and currency entry along with formatting for account numbers. For instance, a date entry format could be set as MM/DD/YYYY and the null format string should show as __/__/____. The user could type in the date of July 23, 2024 by typing in 07232024, with the cursor moving around the slashes after the 07 and the 23. Pressing the slash would move the cursor to the next date section, so the first 9 months could be entered as “7/” instead of 07 with Apex filling in the leading zero.  

Also, numeric format could use this as well. Our accounting system has many departments, sections, account, subaccounts, etc. I'd believe that being able to show the format as “____-_____-_____-_____-___” instead of having it blank hoping the user will fill it in properly would be a big help. (I use this solution from https://unpkg.com/imask@6.0.7/dist/imask.js. I'm sure Oracle could implement this functionality in Apex)
