Thank you Michael. I assume I can help you with that.

I can also help with the editable grid. Editing could be enabled only if 
the table has a primary key or a unique index, for example. I sometimes 
need to edit raw data when something went wrong during the 
development/debugging. (And I tend to be lazy to type an UPDATE 
statement manually although LazDataDesktop offers a template for it :) )
