Hi Thomas,

You really have made good point!!!

It is really have no big sense for SQL editor to have auto-completion!
What user really need -- list of tables and list of fields.

This can be made as 2 keyboard shortcuts!
I need now type name of table, press e.g. Ctrl+T and get popup menu with
tables.
