hotdata-marimo — next steps

Near term (build on MVP)

Workspace selector — When HOTDATA_WORKSPACE is unset and multiple workspaces exist, expose mo.ui.dropdown (or similar) and rebuild the client when the choice changes.
Connection status — Small status chip (API reachable, workspace id, optional sandbox) using a lightweight health or workspaces/connections probe.
Query cancel — Wire cancel to the query-run API if/when exposed in the OpenAPI client; surface a Cancel control next to Run.
mo.ui.hotdata_* aliases — Re-export or thin wrappers: hotdata_sql_editor, hotdata_table_browser, hotdata_query_result, hotdata_connection_picker for discoverability.
Tests — Unit tests with mocked SDK responses; optional integration tests gated on HOTDATA_API_KEY (mirror sdk-python patterns).

Schema-aware autocomplete — anywidget (or CodeMirror) + Hotdata information_schema / column metadata for table/column suggestions.
Async UX — Progress text or spinner while polling query runs; optional configurable timeouts.
Run history panel — QueryRunsApi.list_query_runs + metadata (latency, touched tables, result_id) in a side panel or collapsible.
Rerun / clear — Explicit rerun without relying only on run_button semantics; optional “clear result” action.

Pagination / LIMIT guidance — Surface row counts vs limit; warn when result is truncated if the API exposes it.
Export — CSV / Parquet download links or buttons (align with Hotdata results/export APIs when available).
Cached result reuse — Prefer get_result(result_id) over re-running identical SQL when result_id is known.
Materialization / cache status — Show persistence state when the API returns it (processing / ready / errors).

Connection picker — Filter catalog by connection; map display names to ids consistently.
Schema search — Text filter over tables/columns without loading full dropdowns for huge catalogs.
Table preview — LIMIT preview query from browser selection (optional second query).
Generated queries — Starters beyond SELECT *: profile/join templates from selected tables.

Deployable Marimo app — Layout recipe (sidebar explorer + editor + result) and docs for marimo run / WASM constraints.
Auth in apps — Document env injection for deployed apps; avoid embedding API keys in notebooks.

README — Install, env vars, minimal notebook example, and “two-cell” pattern for editor.result + mo.stop.
Changelog — Keep CHANGELOG.md once versions ship.
