-# nogui
+# fyne
 
 Package gui implements a abstraction layer for Go visual elements.
 
 This is a sample plugin. It's a skeleton intended to be used when making a new toolkit plugin.
+
+fyne appears to require:
+	runtime.LockOSThread() // Ensure main stays on one OS thread
+	a := app.New()
+	w := a.NewWindow("Fyne Plugin Fix")
+	w.ShowAndRun()
+
+error:
+gui doing TestDraw() Forge: (this kinda works sometimes)
+panic: Run() or ShowAndRun() must be called from main goroutine
+
+so for fyne to work, there must be a protocol buffer GO GUI plugin first that
+can spawn and talk to fyne
