Description

I asked this question on the Slack channel. It would be helpful for the Atom UI to better visually distinguish package settings when a config type of object is under another config type of object (as documented here https://atom.io/docs/api/v1.21.1/Config#object--grouping-other-types). When I expand a group headline, all it does it expand/collapse everything under that group. When everything under that group are more objects, they are aligned with the parent headline. Here is the Atom Beautify package, I have Executables expanded right now, but it doesn't visually distinguish them.

Suggestions:

• Indent config type objects that are under another config type object
• Modify the expand icon on the right to show when it's in an expanded state versus a collapsed state
• Use a different background color for configs under a config type object
• Or do all of the above

Steps to Reproduce

1. Install a package with a config that has config type object under another config type object (e.g. Atom Beautify)
2. Open the Settings panel for that package
3. Expand a group headline that has other group headlines under it

Expected behavior: Some way to visually tell they are under the same group

Actual behavior: They look like they are independent of the same group

Reproduces how often: 100%
