On a side-note, I'd love to see an even more minimalist stripped-down, read-mostly query/tabular result only (with pivot tables) tool, which had some local columnar storage caching/query engine, and simple import/export to common file formats as well. A simple "SQL notebook" that was cross platform, if you will, but worked more like a traditional query tool. And not embedded in MS Excel, like PowerQuery or PowerPivot (although it's powerful!).
Something lighter weight than BI tools such as Power BI, Tableau, Qlik, etc., definitely lighter weight than tools such as SSMS, DBeaver, SQuirrel, etc. - not for administrative use. I've seen a few applications that are coming close listed on HN lately, but would be nice to have something as pretty as this and which is open source.
Perhaps a fork with the admin features stripped out, some additional plumbing added, and read-only connections, I'm not sure.
Will have to think about it. Main use case is data scientists / data analysts / SQL power users.
