Atom is a total joke compared to VSC. In ATOM you don’t even have code lookup, or peek.
Say you have a project that has more than 2 source files, and you hover over a function and forgot what file it was placed in. Or you pulled in someones else’s code and have no idea what file that put that function in. What are you going to do? Look in each file for that function in ATOM? In VSC you just right click on that function and it will take you right to it. Or you can right click on it and use peek to see it. VERY handy feature.
ATOM does nothing like this.
