v0.7.0

Ostraplan 0.7.0 adds loose-item placement, makes symmetric building predictable, and fixes ship valuation and RCS ratings.

Make Loose Item / Install item

Right-click a placed fixture — a sink, an appliance, a gas canister — and choose Make Loose Item to uninstall it into its packaged (loose) form on the tile, or Install item to do the reverse.

• Eligibility comes straight from the game's own install/uninstall jobs, so only genuinely uninstallable fixtures are offered (raw hull, walls and the fixed airlock never are).
• The swap keeps the part's tile, rotation and any cargo, in a single undo step.
• Contents are conserved — a gas canister stays charged across the swap.
• A loose fixture stops certifying its room; re-installing into a spot that no longer fits is flagged in Problems rather than blocked.

Placing arbitrary loose inventory (tools, food, consumables) is a separate flow, not in this build yet.

Symmetry now previews every mirror

With symmetry on, the placement ghost shows the cursor part and each of its mirror copies — green where the mirror will land, red (with the offending tiles tinted) where the placement law refuses it. Previously an ill-fitting mirror was a silent no-op, which read as "symmetry only works most of the time", especially on large ships where mirrors more often land on structure that isn't symmetric yet. Now you see exactly what will mirror before you click.

RCS thrusters are built in their ON state

The game installs an RCS cluster Off, and the maneuver rating doesn't count an Off thruster — so a designed ship used to read maneuver "O" and you'd have to power each thruster by hand after loading in game. Ostraplan now builds the identical On variant, so a design shows a real maneuver grade and an exported ship's thrusters work on spawn. (Imported ships keep whatever state they were saved in.)

Fixed: exported ships carry their real broker value

Export used to bake each room's physical volume into its value instead of the game's parts-based room value, so a spawned design read as nearly worthless at a broker until the game recomputed it on full load. It now bakes the same parts value the game does (and that Ostraplan already shows in the inspector).
