Changing "Default Pinned Models" in admin settings had no effect for anyone who had already opened Open WebUI once. The sidebar copied the admin default into that user's own settings the first time it rendered and saved it to the server, which marked them as having customized their pins, so every later change to the default was ignored for them. Merely loading the page was enough, the user never had to touch a pin.
The default is now resolved for display only, through a shared store that falls back to the admin list while the user has no pins of their own, the same way default models already work. Nothing is written to the user's settings until they actually pin, unpin or reorder something, at which point their choice takes over for good. Unpinning everything still persists an empty list rather than snapping back to the default.
Users whose settings were already overwritten by the old behaviour keep that copy, since a stored pin list cannot be told apart from a deliberate one.
Fixes a drag-reorder path that mixed sidebar positions with stored ones, and stops the sidebar section reopening itself after any unrelated settings change.
On narrow viewports the admin Models list rows previously collapsed into
unusable vertical stacks; the Models page redesign on dev has since
absorbed the truncation fixes this branch carried (min-w-0 chain, real
truncate on the name, shrink-0 action group, inline access label).
The one remaining gap: the per-row edit pencil duplicates the row tap
(both open the model editor) while costing scarce horizontal space on
mobile. Hide it below the sm breakpoint; it remains on sm+ screens.
