MeshMonitor v4.9.3 gives Position Estimation the home and the controls it deserved. The feature that plots a best-guess location for nodes that never report GPS — by pooling traceroute and NeighborInfo geometry across all your Meshtastic sources — is now where you'd expect to find it, with a new knob to keep the map tidy.

It lives in Global Settings now

Position Estimation is a single, global, cross-source batch job: one schedule, one set of estimates shared by every source. So it no longer hides inside a per-source Automation tab — it now sits in Global Settings → Position Estimation (the ⚙️ gear in the dashboard sidebar), gated by settings:write to match how the backend has always treated it. Enable it, pick a calculation frequency and lookback window, and hit Recalculate now whenever you want a fresh pass.

Tame the circles: Maximum acceptable accuracy

Estimates come with an honest uncertainty radius. A node seen from a single anchor can only be placed "somewhere within radio range" — a ~5 km circle — while a node triangulated from several directions lands in a tight one. On a dense map those big single-anchor circles can take over.

The new Maximum acceptable accuracy (km) setting fixes that: any estimate whose radius exceeds your cutoff is discarded instead of stored, and stale estimates that no longer qualify are cleared automatically. Set it to ~2–3 km to drop the loosest guesses and keep only the confident ones. Leave it at 0 for no limit. The last-run summary tells you how many were discarded.

One toggle for accuracy

The estimated-position uncertainty circles are now controlled by the existing Show Accuracy toggle in the Map Features panel — the same switch that governs the precision regions for GPS nodes. So one control governs every accuracy overlay: turn it off to declutter, on to inspect. The estimated markers themselves stay under Show Estimated Positions.

A few Sources sidebar refinements landed alongside: an Edit mode that hides the drag-to-reorder handles until you want them, a resizable sidebar (great for long MQTT source names), and a fix so each source's node count stays consistent no matter which source is selected. The settings page section-nav buttons now reliably scroll to their sections too.
