UI Refresh, Requirements Management, and Other Improvements
UI Refresh, Requirements Management, and Other Improvements
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 Re-Design
High‑traffic editing surfaces are cleaner and more powerful.

Requirements page uses a compact requirement list for improved readability.
Right sidebar includes an overview of requirement stats.
Click a requirement to edit 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 group or sort the requirements list
Set various requirement properties on right-click:

NEW: Requirement Tab
Requirements now each have their own page to support long-form content. All existing properties remain in the right sidebar and can also be accessed through the context menu.

Main section includes an editor for long-form content and a list of sub-requirements underneath
Right Sidebar shows other requirement properties, constraints, 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.
In the TabHeader > State Dropdown, transition to a state containing substates. You will see additional options to transition to substates
When selecting a transition, in Right Sidebar > Element Properties, define guard conditions for transitions by selecting a variable, operator, and limit. Blocked transitions are highlighted in red.
