kUML v0.55.3 — Desktop: dialogs that actually show up, ⌘ shortcuts on macOS

kUML is a Kotlin DSL and toolchain for UML, SysML 2, C4, BPMN and more. This is a Desktop polish release.

• "New Workspace…" and the workspace trust dialog were Compose popups drawn inside the main window. Compose does not paint popups over heavyweight Swing components, and the editor and the SVG preview are exactly that, so the dialogs opened invisibly or cut off. They are real dialog windows now.
• Menu shortcuts were KeyShortcut(ctrl = true) everywhere, and Compose Desktop does not map ctrl to ⌘. Everything goes through one platformShortcut helper now: ⌘ on macOS, Ctrl on Windows and Linux.
• Workspace document header: Read/Edit as tabs above the content, type and title aligned. Scripts saved in an Engineering workspace now appear in the tree (it was scanned only once on open).

Built & Monetized 2 Native Android Apps (Kotlin): A Placement Prep Quiz App & 2D Flappy Bird Game. Need Feedback!

Hey everyone,

I recently built and deployed two native Android applications using Kotlin and Android Studio, focusing on optimized app performance and monetization integration.

• Tech & Placement Quiz App
* Features: Curated questions on DSA, Core CS, Quantitative Aptitude (SSC CGL/Placement level), and 2026 Current Affairs.

* Tech: Integrated Start.io (http://Start.io) SDK for monetization and built dynamic deduplication logic using SharedPreferences to prevent repeating questions in sessions.

* 🔗 Dawnload : https://ankursinhagames.itch.io/quiz-app

• Flappy Bird 2D Game
* Features: Custom Canvas rendering, frame-rate responsive touch physics, dynamic obstacle generation, and local high-score tracking.

* Tech: Integrated Start.io (http://Start.io) SDK for ads.

* 🔗 Dawnload : https://ankursinhagames.itch.io/sky-dash

Would love to get your thoughts on the code structure, UI/UX, and performance. Feedback and suggestions are highly appreciated!
