Yesterday, I used the SDF with WebStorm. The experience is great compared to how I was imagining it. Now today, I opened the same project in WebStorm and it only loaded up as a normal project and not as Account Customization/SDF project. The "NetSuite" option in the right-click menu is also grayed out/disabled. How to fix this? Figured it out.

What was it?

Opened the root folder instead of the actual project folder.
