I've recently been trying to find a good SQL TUI client, and one of the ones I tried was Harlequin. The main disadvantage, which every other SQL TUI I tried also suffers from, is that they don't comprehensively show every type of database object in the browser pane (e.g. tables, views, indexes, procedures). For example Harlequin only shows tables. This means that when you want to view one of the missing ones, you have to run a query. This means that you have to already know that the object you are looking for exists: there's no way to get a good overview of what you have in the database just by glancing at the browser. For me this sort of defeats the point of having a TUI in the first place.

It seems like the OP's offering has the same problem, although it does offer more objects than Harlequin. I'll be bookmarking it to see how it develops.
