 ### Changed
 
+- **Transparent Stream copy buttons now confirm success in place.** The tool-event and thinking copy controls flash a check for ~1.5s after a successful copy — the same feedback the normal chat copy buttons already give — then revert to the copy glyph. The confirmation is now clearly visible without hover (important on touch), stays correct across live-row reconciliation, cleans up if its row is torn down mid-feedback, and is never serialized into a restored session snapshot. Thanks @Stacey2911. (#6037)
+
 - **Kanban boards can now set a default workspace path.** The board settings modal gains a "Default workspace path" field (a type-or-pick combobox sourced from your saved workspaces, so you can choose a known path or type a custom one — validated server-side). Tasks on the board without an explicit workspace path inherit this default. The board switcher chip is now always shown (even with a single board) and its menu item is now "Board settings…", enabled for the default board. Thanks @rodboev. (#6055, #5932)
 
 - **The workspace file tree can now be sorted, and the "Show hidden files" toggle moved into a menu.** The workspace pane's ⋮ options menu gains a "Sort by" group — Name (A→Z), Name (Z→A), Date created, Date modified — and your choice persists across sessions. "Date created" is disabled with an inline note on platforms/servers that don't report creation time. The pre-existing "Show hidden files" toggle moves from a permanent inline row into that same menu, reclaiming vertical space on every workspace view; a small indicator on the heading still reflects when hidden files are shown. Thanks @rodboev. (#6091, #6066)
