I've never used navicat but for dbeaver, its not at parity because dbeaver offers a lot of features which it doesn't yet.

The data destruction thing was something I was really careful with, any destructive query opens a confirmation first, any edit opens a popup showing the query that will run. I've designed it to be really safe.

For perf, even if row listing speed doesn't matter I assume scrolling and loading a large dataset would improve your workflow, plus quick tab switches and low memory usage for all, no?
