Ability to resize columns in IMPORTS & IMPORT DATA SOURCES

Description of the enhancement required:

To get workspace more user friendly for models developers. 
I know that I can copy-paste to excel and read all hidden letters / words.

An example of the enhancement:
Step 1 click right mouse buton (choose "Column settings")
Step 2 confirm column width and get better view (small improve but significantly improve work for developers).

A story for why they want the enhancement:
This would be an improvement for the model developers (people which work in background to build all modules and dashboards) not for the people which operate on dashboards.
