Has there been any talk of HTML rendering in Godot, maybe even a 3rd party module?
There are no plans to feature a WebView such as CEF for various reasons:
- They are huge – they can take hours to build, and greatly increase the file size of the produced binaries.
- They perform worse than native GUIs, and rarely integrate well with the rest of a game.
It should be possible to write a module to implement a WebView within Godot, but it's probably quite hard and I'm not aware of any existing implementation. I am aware of libraries like libRocket, but the feature set is limited and it's barely maintained nowadays; also, its performance isn't really good (in the few games I play which use that library, it's always been a CPU hog).
Profiling - I spend a LOT of time in the Unity profiler. I haven't tested out Godot's profiler too much yet, but from my initial impression it seemed a bit difficult to navigate.
The profiling tools could be more complete and easier to use (I'd like to see a built-in FPS graph/counter and rendering information box that you can overlay on a running game, for example). If you have ideas of possible improvements, you can submit issue reports on GitHub – make sure to include potential use cases or benefits when requesting a feature.
IDE - When support C# rolls out will can we expect support for external editors such as Visual Studio?
Indeed, the plan is to support external IDEs like Visual Studio, Visual Studio Code, MonoDevelop or Rider, as there won't be a built-in C# editor in Godot, at least for now.
Also, has there been any word on referencing external dlls/plugins for use within the C# environment?
I'm not sure about the C# specifics, but Godot 3.0 will make it possible to link dynamic libraries using GDNative, which opens new possibilities (such as extending Godot without recompiling the whole engine, or making it more convenient to use C++ for game logic).
