Maybe I'm missing something, but I find the process of developing/modifying an extension such a PITA on vscode. In sublime it's frictionless, all you have to do is to save some python files in your user folder, then sublime will find them automatically, and hot reload them when you modify them! In VSCode, I have go through a whole build process, generate some .vsx and then manually install it. The tiniest modification to the code requires me to go through this whole process again. Am I doing something wrong here?
