 | 20 | L | Open original level | The description was clipped (the dialog was packed before the text was set), and the selected row's id was grey on orange. | **Fixed** |
 | 21 | L | Status bar | The last-build label was cut ("Built 03:37:16 · 6158 KB · 2 w…"). | **Fixed**: "Built 03:37 · 6.0 MB · 2 warnings" |
 | 22 | M | New level | A new level keeps the base level's 13 zones and 30 lights. Their outlines float far from the 16×14 floor (pink boxes in the sky), which is confusing in an empty level. | **Fixed (0.2.0)**: new projects keep only the start zone and the directional lights; teleport zones, point lights, waypoints and region masks of the base are removed (stored as edits, old projects unchanged). Directional light markers are drawn above the player start |
-| 23 | M | Play-test | While the game runs, nothing in the editor says so: the status line falls back to "Ready" after 6 s. | Not fixed. It needs a sticky status or a "Playing…" state of the Play button (a shell API addition) |
-| 24 | L | Shift+F5 | There is no mark in the viewport showing which point "the middle of the view" is. | Not fixed. Suggestion: a small crosshair while Shift is held |

+| 24 | L | Shift+F5 | There is no mark in the viewport showing which point "the middle of the view" is. | Fixed (edui): crosshair in the middle of the viewport while Shift is held (300 ms delay, hidden while a mouse button is down) or while *Play from camera position* is hovered; green = valid start, red = not (status bar says why) – `tools.playtest.PlayHereMarker`, `Viewport.setHudOverlay` |
+| 25 | L | Outliner | Rows show technical ids (`brush:n19`, `strat:6`). Several brushes are all called "Floor". | Fixed (edui): rows read "Coin 3", "Floor 2", "Waypoint 4", "Chain 1 – Llama", "Light 2", "Model 12 (…)", position/height in the grey column; the id is the row tooltip (filter still matches ids) |
