I am not a scientist, but an artist and a game designer.
GPlates should be able to read vector data and use that instead of users having to rebuild in GPlates with the slower and less accurate Drawing Tools.
Autodigitize from vector or raster image

I came across GPlates form other designers who are using it in conjunction with QGIS to create fantasy worlds with real coordinated and what have you.
Though GPlates imports SVG’s, it doesn’t import the vector data. Is this perhaps something that the team has considered? Making it easier for someone like myself who sets stuff up in Adobe Illustrator. Then I can import the vector SVG, do what I need to in GPlates and then export it for further GIS work.
The vector data can be quite detailed for coastlines or tectonic plates. Having to retrace something I did in Illustrator or other vector daring program is a hassle in GPlates.
Being able to take that data on this path:
Vector Drawing Program > GPlates > GIS Software (QGIS, etc.) > World Machine > Video Game Engine (Unreal/Unity) or to Print for Table Top Games
Would make creating full fleshed out worlds amazing and easy.
