Describe the feature you're suggesting.
There's a lot of customizations in the m0rehud folder that aren't in the editor. They should be added to the schema.

Changes are being made in a separate branch here: https://github.com/CriticalFlaw/TF2HUD.Editor/tree/%23194

Development complete. A change to the editor was required, which is why this will be released in version 3.2 of the editor.
