A canvas grid wrapper aiming at the row counts where R's HTML table widgets stop being usable.
cheetahR wraps the Cheetah Grid JavaScript library as an R htmlwidget, positioned by its authors as an alternative to reactable for large datasets. The Shiny surface is now substantial: proxy functions, numeric and date column formatters, sorting, search, column groups, inline and menu cell editors, and a get_grid_data() helper that returns live grid contents as a reactive data frame. The most recent release adds an autocomplete column that suggests values from a list while still accepting free text.
Knock is hardening for enterprise buyers while its agent takes over the analysis work.
Knock ships weekly, in small, legible increments across three lanes: account governance (custom roles, passkeys), workflow primitives (wait-for-event, branch rebasing), and data ingress (Amplitude, Clay). The newest entry adds granular custom roles, which closes the last obvious gap in account-level access control. Alongside that, the in-product agent gained analytics, letting teams interrogate delivery performance without building reports.

The most recent release adds an autocomplete column that suggests values from a list while still accepting free text.
The arc moves from rendering to editing. Early releases added the read-side affordances a table needs, sorting, search and column grouping, while the last two have been about the grid as an input: proxy functions, cell editors, a typeahead column, and a way to read the edited state back into Shiny. The releases are sparse, roughly three in fourteen months, so this is steady rather than fast work, and the fix in 0.4.0 for renderCheetah() stacking duplicate grids suggests the Shiny integration is still being shaken out under real reactive use.
The editing thread points at more column action types and validation on committed values, since an autocomplete that accepts arbitrary text leaves the checking to the app. The performance claim that motivates the package is asserted rather than measured anywhere in these entries.

Two arcs run in parallel. The infrastructure lane is buying enterprise credibility — roles, passkeys, audit-grade permissions — the checklist items that decide procurement rather than daily use. The data lane keeps widening what can trigger a workflow: product analytics from Amplitude, enriched rows from Clay, internal Slack channels as a destination. Together they push Knock from a notification API toward the messaging control plane, with the agent as the layer that explains what the plane did.
Expect the roles work to continue into audit logs or scoped API keys, since granular permissions without an activity trail is an incomplete enterprise story. More data sources are likely on the same cadence, with the CRM and warehouse categories the obvious remaining gaps.
