It would be great to allow text fields to be read from XML instead of entering text content layer-by-layer. This would reduce duplication. For example, an XML file with a tag could have that tag read by a MimoCall layer, a lower third layer and a scrolling credits layer.
In esports, the tag could be read by a flying text “team vs team” layer, an on-screen team identifier layer, and a scoreboard layer.
It would also allow the use of third party apps that generate output to XML files, such as the Scoreboard Assistant commonly used at eSports events.
