+## Round 25 — folder highlight while dragging a playlist (v0.1.6)
+
+Tests in `tests/test_round25.py`. Fix round → patch bump **0.1.6**.
+
+Dragging a playlist over a folder gave no indication the drop would land
+inside it. `PlaylistTree` now highlights the hovered folder mid-drag with the
+same treatment track drops give playlist rows, via a shared
+`_highlight_drop_target(pos, kind)` helper ("folder" for internal moves,
+"playlist" for track drops). A folder in the dragged row's own branch is
+never highlighted — `move_playlist` rejects that drop as a cycle, so lighting
+it up would lie. The Round 24 autoscroll tick's highlight refresh became
+kind-aware (`_drag_target_kind`) so a folder highlight survives edge
+auto-scrolling instead of being cleared by the track-only check.
+
+- [x] `lintunes/gui/sidebar.py` — `_highlight_drop_target` /
+      `_is_own_branch` helpers; `_drag_target_kind` tracked through
+      `dragMoveEvent`, reset in `_stop_autoscroll`.
+
 ## Round 24 — sidebar drag auto-scroll (v0.1.5)
 
 Tests in `tests/test_round24.py`. Fix round → patch bump **0.1.5**.
