I initially posted this as a bug and was told to refile as a feature request:
Using PCmanFM-1.2.1/LibFM-1.2.2.1 on slackware64-current. With View > Sort Files Ascending By Name selected and ignore case not checked I get the expected sort order in the Folder / File Pane, but the Directory Tree (leftmost column) ignores the sort order, /bin comes before /Desktop.
Further, I have my environment set to LC_COLLATE=C which should also set sorting to (e.g.) AABBCCDD...aabbccdd....
Request Directory Tree follow same sort order as the File Pane. Thank you.
