Kickstarting 2025: Software Ideas Modeler with Optimized Performance

We have been hard at work optimizing Software Ideas Modeler to provide a seamless experience when dealing with diagrams containing hundreds or even thousands of elements. To achieve this, we enhanced the diagram preview (navigator) sidebar so it now updates its content in the background. This means you can continue refining your designs without interruptions, making your workflow more efficient than ever.

In addition to these performance optimizations, we have resolved several discovered issues to ensure maximum stability and reliability. Whether you are creating standard UML diagrams, wireframes, or complex user flows, you’ll find our UML tool for 2025 even more robust and responsive.

For users working on wireframes and user interface designs, we have introduced a convenient new feature: simply drag a UI Diagram from the project tree and drop it onto the Screen Flow Diagram canvas, and a corresponding Screen element will be created automatically—saving you time and maintaining a clear connection between your interface prototypes and their flow structure.

Create a screen flow diagram by dragging and dropping UI diagram node from the tree view

Try out the newest version of Software Ideas Modeler today and discover a faster, more intuitive way to bring your design ideas to life. We look forward to your feedback and continuing to provide the best diagramming software for 2025 and beyond!
