StageInfo

Extra info and flight performance readouts in the stock staging window for Kitten Space Agency.

The stock staging window computes per-sequence Delta V and TWR in the vehicle editor only, with a fixed vacuum / sea-level toggle. StageInfo adds its readouts to the same window (both the Sequences and the Resource Groups tab) so they also work in flight, and goes deeper: burn time, ISP, TWR against a selectable body's gravity, live fuel state, RCS budgets, and a corrected multi-stage burn duration for auto-burns.

A mode selector sits at the top of each tab; per-sequence and per-group numbers render inline in the tree (with fuel and RCS bars on each header), and the vehicle totals sit in a footer below. The stock window keeps full ownership of the tree and all editing; StageInfo only adds numbers.

Features

• Per-sequence Delta V, TWR, burn time, ISP, and live fuel fraction in flight. A fuel bar sits on each sequence header; expand a sequence to see the numbers inline, above its parts. When a burn is planned, the row shows how much of its dV the burn consumes, colored green to red by consumption.
• Per-group mass, fuel pool, engine count, decoupler count on the Resource Groups tab, inline under each group with a fuel bar and an RCS bar on the group header. Substances no active main engine can consume are listed as RCS entries (e.g. MMH 1,180/1,761 kg) with a hover tooltip for the full substance name and current/max mass. Shared tanks (e.g. LFOX feeding both the main engine and a vernier thruster) stay in the main fuel pool so nothing is counted twice.
• RCS dV budget as a footer line (RCS dV ~X m/s). Hover for an engineering tooltip listing effective ISP, total propellant, and scalar peak thrust.
• Display modes Auto / VAC / ASL / VAC+ASL / Planning for previewing dV under different ambient conditions (Planning lets you pick any celestial body in the current system).
• Editor readouts in the vehicle editor's staging window: the same per-sequence Delta V / TWR / burn time / ISP line, with a body selector for the TWR reference gravity and a Vacuum toggle for bodies with atmosphere. The stock editor also shows dV/TWR, but fixed to standard gravity and a vacuum / sea-level toggle; StageInfo's numbers account for the selected body's gravity and reachable-only propellant.
• Totals footer with total Delta V, planned burn dV, and burn time. Turns red when the planned burn exceeds available dV.
• Corrected burn duration for multi-stage burns: the stock game computes burn duration as if the full dV came from the current stage, which underestimates the time for staged burns. StageInfo rewrites the BurnDuration shown in the burn gauge and, more importantly, the IgnitionTime used by the auto-burn logic, so staged burns ignite at the correct lead time.

Installation

1. Install StarMap.
2. Extract the SpaceDock zip into Documents\My Games\Kitten Space Agency\mods\StageInfo\.
