From 920284009d634cb568f95b3e93b93012c4b803bb Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Sun, 6 Sep 2026 23:42:59 +0200 Subject: feat(client): bring back New folder, icon-only — and close the hole it opened MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The control was hidden and its `canCreateDir` left computed and unused. It is back in the Files toolbar as an icon: the toolbar already carries one labelled primary action, and a second beside it competes for the width the breadcrumb trail needs. The name is in `title` *and* `aria-label` — a title is invisible to a screen reader on a button with no text, so an icon-only control without both is simply unnamed for anyone not reading with their eyes. Its gate changes. It required `isNodeAdmin`, which contradicted the node's own rule — "making a directory is not a privileged act; a member who can add a file can organise where it goes" — and hid the control from everyone who could have used it. It now follows the Upload button: a writable root, and not at the top of a group, where the level is the set of roots rather than a directory on anyone's disk. Restoring it surfaced a real gap. `_do_dir_create` never learned about RO/RW: `_do_file_upload` gained the `writable` check with the model and this one did not, so a member refused a file in a published library could still leave empty directories all through it, and could write to a drive mid-eject. Read-only has to mean read-only for every way of writing, not just for files.
