Provide specialized fields when inserting/modifying data with Data Explorer

[jquesada2016]

It would be fantastic if inserting data in the data explorer has specialized inputs depending on the input type.

For example, when a property type is datetime, you have to type the full ISO datetime string manually. Can we have a calendar and time picker to more quickly generate the datetime string?

Also, when adding to a property of type bytes, it would be great if we had the option for both base64 strings and a file upload button. Previewing images would be awesome, but I can imagine why this would not be the easiest thing to support. Downloading bytes would be very nice too.
