Thanks for the post, but as is mentioned in the header of this forum, it isn’t meant for feature requests. So I’ll have to close this thread.
I’ll note though that it’s not really string fields that are needed here, but geometry fields, because the result of the string to curves node would be different for every point. While that’s theoretically possible, it also opens the doors to a LOT of complexity, and we made the decision not to do that a while ago, so we could always have the simplicity of “geometry data is passed with real data-flow”. Loops will likely be the way to address this use case, or a separate “Text Distribute” node that uses a string field input. There’s more discussion about this stuff here: Text mograph nodes design
