I suppose the tooling for databases (or the expectation from users) means they all end up sharing a similar UI and where and how various features are implemented. Not too unlike word processors or spreadsheet software!
Somehow not really liking the fork.
When I started building Beekeeper there were 0 open source DB apps with good UX, especially on Linux. So that's why it exists.
I now have a paid version to support development as it has grown super quickly over the last 3 years.
These graphical database clients mostly end up looking the same in the end.
Simplicity and ease of use vary a lot between them.
