Qt Qml Profiler

Runs qmlprofiler on your Qt Quick app, parses the trace, and spits out hotspots with frame time, memory, and pixmap cache stats. Works when your UI feels laggy or when you explicitly want to profile bindings, signals, or rendering. It'll locate your Qt install, rebuild with QML debugging flags if needed, run the profiler with the right feature sets (full, rendering, logic, or memory), and analyze the results against your source. Only handles 2D Quick apps, not Quick 3D, so if you're profiling a 3D scene you'll miss those bottlenecks. Saves you from clicking around Qt Creator's profiler UI when you want to stay in the terminal.
