It would be nice to be able to change the folder indentation in the Project view, either by the theme or a control.
The current folder indentation takes a lot of space compared to VSCode for example. Some people might like it as it is but for other people, this might take too much screen real estate, especially on a 13' laptop.
Compared to VSCode the Project View in Webstorm is 55px bigger.
Another thing is the horizontal scrolling of the Project Folder. Most of the times it happens because of the unnecessary folder path in the Root of the project, but again comparing to VSCode the idea of adding an ellipsis to the file and folder names is really nice.
