Question: I feel comfortable working with 4-space indentation. However, most of my colleagues want 2 spaces. The linter is set up for 2 spaces.

Is there any way to make WebStorm displays 2 spaces the same size as 4 spaces? So when the code on my local machine would display the way I want and the way the others want on other machines.

Answer: 
Currently, there is no way to achieve that. Feel free to vote for "Virtual indents" feature on YouTrack: <https://youtrack.jetbrains.com/issue/IDEA-237957>
The [Elastic Indents plugin](https://plugins.jetbrains.com/plugin/14849-elastic-indents) seems to do what you want (I haven't tried it myself).
