The list column showed every type's tree (raw folder names, [Root] rows with 0, nothing marking
where you are), repeating the type chips above it. Now (ui_folder_list.js) it follows the chips:
the type's heading with "📂 Open", All, its subfolders as a tree whose numbers count their
subfolders (empty ones dimmed, folding per session in owner.collapsedFolders), and "In the top
folder" for models directly in the type's folder; the listed one is marked.
A Bilibili comment asked for quick ways to open model folders: POST /anomalous/open_model_folder
without a file name now opens the folder itself (type root or subfolder; still by type, index
and subfolder, never a path, local only). Tests in tests/test_model_folder.py.
Gone: the every-type tree, Expand / Collapse all, expandedFolders and their locale keys.
