Selecting of the variable's datatype from the pop-up which was in the last version. But in the new version we have to select it from the dropdown which is very time consuming and not appropriate for the long drop down options.

While selecting records of lists or list of records we have to spent lot of time to follow the steps and last it not get what we desired. 

If there will be a pop-up open when double clicking the datatype it will be very easy to select the datatype very easily and fast, it will help us for the productivity plus time saving.
