Source-tree package for atom?

Hi guys,

does anyone know a working source-tree package for atom? Meaning: some package that shows me a list of current constants, classes, methods in the current file?

Iā€™d love to introduce a bit more IDE feeling and add something es2015-compatible like https://github.com/xndcn/symbols-tree-view. After searching for a while I have found nothing neat, so this is my shoutout. :slight_smile:

Any tips?
