Toolbox App 3.5: Better Remote Development Observability, More Reliable Enterprise Configuration, and Smoother Everyday Interactions

Toolbox App 3.5 focuses on making daily work smoother and managed development environments easier to monitor. The app now supports interface zooming with familiar shortcuts, provides OpenTelemetry metrics for enterprise remote development connections, and handles several long-standing reliability issues more gracefully.

Remote development observability

The Toolbox App now emits OpenTelemetry metrics for remote development connection latency and reliability. You can send them to Grafana, Datadog, Prometheus, or another OTEL-compatible stack to monitor connection health across your developer fleet.

Zoom controls

You can now zoom the Toolbox App interface using familiar keyboard shortcuts: Cmd/Ctrl + to zoom in, Cmd/Ctrl – to zoom out, and Cmd/Ctrl 0 to reset. The setting persists across restarts, so your preferred zoom level is preserved.

Cleaner update progress

Checking for updates no longer hides behind a generic spinner. You’ll now see what the app is checking, what it’s unpacking, and how far along it is – providing a clearer sense of progress.

Enterprise configuration

For enterprise customers using JetBrains IDE Services, the Toolbox App now sends static and dynamic headers together when communicating with backend services. Header updates are also pushed automatically to running IDEs – no need to restart an IDE to pick up new headers.

Bug fixes

• IntelliJ-based IDEs no longer randomly disappear from the Toolbox App home view. 
• Android Studio and other aliased IDEs keep their display name after updates.
• The taskbar icon on KDE Plasma 6.6 and the tray and app icons on Pop!_OS now appear reliably.

Remote development fixes

• SSH canonicalization failures no longer abort the connection.
• The remote development environment list no longer shows an empty page when the canCreateNewEnvironments flag is set.
