One surface replaces the tab-and-list picker: search or scroll a grouped flat list on the left, configure with a live expression preview on the right. EODHD parity is a badge on every row, not a discovery. ↑↓ move, Enter stages, Enter again applies, Esc closes. Catalog below is the real 33-study registry.
Six category tabs become sticky group headers in one scrollable list. Every study is one keystroke or one glance away; search narrows across all groups.
The ◆ badge rides every row. Server-side-only studies (Ichimoku displacement, sessioned pivots) are listed but marked, not silently missing.
The pill previews exactly what lands in the study strip and the saved study — BBANDS(20, 2.0) — so config and chart never disagree about identity.
