Customised Properties - Limit Character Entry

[bacowarrior]

Hi all,

 

I am building a personalised products store but want to know if the max character length can be set for each individual product (some products need a limit of 14 characters and some have a limit of 25).

 

Also if this can be done, can

1) character countdown be added (14 characters remaining)

2) when you leave this blank and click Add to Cart, a pop up appears saying "Please fill in all the required fields before saving your customization.". Is it possible the fields be highlighted so customers know what they have to edit?
