[ Unified UI ] Create App Updates & Refactoring

[Armored-Dragon]

The Create app (edit.js) is a very large application and it can be very difficult to maintain. There are also performance issues that may be better resolved by a rewrite, or at least a huge refactor. It would also be a good time to clear out a lot of tech debt gathered in the past ten years this script has been chugging along.

Here's my general thoughts on potential improvements to a new create app:

• In-interface view mode & external window mode
  There are a lot of sandbox applications that will overlay all of the editor interface elements.
  See The-Mirror, Trailmakers.
  The external window mode will still be extremely useful and won't be going away. This mode will also be required in the meantime for users in VR.
• Asset server browser
  This should also be refactored also using elements from the main Entity List window.
• Grid visual
  A grid visual as you are building would be very useful so you have a visual indication where models will be placed in the world relative to the global space (or local space?).
• Voxel Mode
  A careful attention will be made to the voxel mode. It's possible support for this could be greatly improved and allow quick swapping between modes when swapping should take place.
• Tree entity list
  • Drag and drop to re-parent
  • Filter between different types, names, locked status, etc.
• A free cam mode to make editing the world easier and not be restrained by your avatar.
• Generally easier material workflow
  • Material saving & quick loading
  • View attached materials to objects
• Centered scaling on meshes

This is going to be a monumental task as this application is a huge part of Overte. Ideas, thoughts, opinions, and testing are extremely valuable.
