a package that sorts the file tree view by file type?
This is talking about it
but no way to actually do it?
Could be a feature request for tree-view-finder package.
Edit: LOL, apparently it’s already asked.
This might be useful to you: https://atom.io/packages/tree-view-sort
It allows for a sort by file type then by alphabet. At least until it’s added to tree-view-finder
