Right now validation happens on the server side AFTER the user has submitted the edit modal and the query is run to the underlying DB. So if a user enters some text that is too long and goes over the length that the DB column expects, they receive a MSQL error message.
It would be great if on the frontend those fields could firstly be limited using HTML attributes such as the maxlength attribute for input fields.
The server side validation would still stay in place, but this new feature would help save time and make the user experience better
