I searched and found some issues/threads about this topic:
Core$1555 Goto Anything: period (for current directory) in paths should be understood
atom$7110 application:open-file should default to the directory where the currently viewed file resides
- Goto Anything could show paths relative to project directories
I think it should just a simple package which follow the current file and list the current folder files and folders, allowing to open them.
Is there some package which does this already?
