Auto-adjust rows height in the Variable Explorer

Description

What steps will reproduce the problem?

Please, look at the screenshot that I attached below.

What is the expected output? What do you see instead? Everything is okay.

Please provide any additional information below

1. It would be nice to have an option to reduce the row height to the minimum by default. Please, take a look at the screenshot that I attached
2. In addition, how about an option that removes the coloring of different data types in the Variable Explorer? The coloring just duplicates the information that is already contained in the “Type” column.

I meant that in #3675 I’m only going to fix the auto-adjustment of rows height. So if you don’t want us to forget on adding an option to turn off coloring, please open a new issue 😃

Hi @vdyashin thanks for the comments, we understand how this can be useful, we will try to work on this for the 3.1 release
