I think stack has helped in that area. As a beginner, I found stack's ability to create a new project from a template very useful when getting started with projects.

The plugins for vim and Atom do a really good job for auto-completion and showing linter/compiler warnings, but they are a bit hard to setup initially.

And they graduate from "a bit hard" to "downright painful" if you want to do it in windows. The consequences of doing it wrong can be severe[1].

+1 yes! The stack new project templates have saved me a lot of time. Stack, I'm general, is a great improvement in my device work flow.
