Highlights

This release adds Command Variants — a fast way to run the same tool in multiple “modes” right from the toolbar. You can assign a different preset to each variant, so your most common workflows are always one click (or one hotkey) away. We also improved the update experience with clearer guidance, reliable cancellation, and a more robust silent installer.

New Features

Command Variants (Preset-based)

• Split-button variants: Selected commands now appear as split buttons with additional variants in the dropdown.

• One preset per variant: Each variant can be linked to a specific settings preset, letting you run the same command with different configurations.

• How to assign a preset:

  1. Open Settings

  2. Select a command in the left navigation

  3. Select or create a preset (top dropdown)

  4. Assign a Variant to that preset (dropdown next to presets)

• Execution behavior:

  • Running the main command always opens the settings form first.

  • Running a variant uses its assigned preset and opens the settings form only if one or more inputs are invalid.

• Example (Run Dynamo): Create presets for different .dyn files (or the same file with different input values), assign them to variants, and launch them instantly from the toolbar — including via hotkeys.

Run Dynamo

• FROM SCRIPT: Added a FROM SCRIPT button that reads the list of input values from the selected .dyn file and automatically fills/updates the inputs in settings.

Improvements
