Interesting, but I think it works only for quick ad-hoc analysis. For dashboards or deeper research, you still need other tools

Yes, that's exactly its main purpose! I initially started because I needed a dataset browser. I work with clinical trials, so we usually get raw data files in all possible formats, from CSV to EXCEL and, of course, SAS formats. But since I was already using DuckDB, I thought about extending it a bit further, so you can quickly get a glance at the data.
