UI refresh; navigation improvements, richer requirements editor

Re-designed core UI pages and components, improved navigation, and the requirements page has been rebuilt for streamlined search and editing.

Architecture Re-design

Refined node styling for improved readability and contrast. Interactions and behavior remain unchanged. Added hyperlinked badges in the Sub parts, actions, and states sections for better navigation.

Requirements editor

High‑traffic editing surfaces are cleaner and more powerful.

How to use it:

  • Requirements page uses compact requirement “pills” for dense, scannable lists
  • Click a requirement to open details; use the new context menu for setting requirement Status, Type, Parent, and more
  • From the Left Sidebar requirements tree, double-click an item to scroll the view to it
  • Open Display Options to sort by field and choose compact layout

NEW Requirement Tabs / Internal view

Requirements now each have their own page to support a main editor for long-form content. All existing properties remain in the right sidebar or can be accessed through the context menu on the root requirements page.

  • Main editor uses clearer typography and spacing for long‑form content
  • Right Sidebar groups properties, constraints, and system assignments for quicker scanning

Navigation Improvements

We introduced temporary tabs (shown in italics) to keep your workspace tidy as you move around. Double‑click a temporary tab to make it permanent, or open a permanent tab directly from requirement and node context menus.

Copilot redesign

A cleaner layout with improved context visibility and streamlined actions.

Richer state modeling: Substates and transition guards

Model hierarchical behavior with substates and add guard conditions to transitions for precise control.

How to use it:

  • In the TabHeader > State Dropdown, transition to a state containing substates. You will see additional options to transition to substates
    Image: substates
  • In Right Sidebar > Transition, define guard conditions for transitions by selecting a variable, operator, and limit. Blocked transitions are highlighted in red.
