We're definitely looking to add back some of that flexibility / customizability. I don't think you have to sacrifice a nice, simple UI to provide what power users are looking for.

For now, the main reasons for a prosumer to use over oobabooga/sillytavern are around the base tool set we provide and the "agent loop". If you ever want to use your single chat interface to do data analysis (code interpreter), multi-step realtime research (deep research), or RAG over large scale data (hybrid search), Onyx would be a particularly good choice.
