I've just submitted v1.2.0 of the DbIo to the plugins' area and will post back here when it's available for download.
This version contains a *major *restructuring of the Tools->Database I/O Manager layout to reduce clutter and make currently-selected handler the "focus" of all actions. It also includes a new concept: export customization. The export-customization, currently available for the Orders and Products handlers, allows you to select only the fields that you "want to see" and the order in which those fields are exported.
The following changes are included, identified by their GitHub repository issue number:
#59: Enable custom exports
#76: Restructure Database I/O Manager layout
#83: Maintain last-selected file's location
#84: Don't automatically render a handler's filters (performance)
#85: Enable download or removal of DbIo-generated logs
#86: Add a handler to support manufacturers' import/export
#87: Ensure that character fields' defined length is enforced
#88: Use a text-link instead of an icon to identify that import results are available
#89: Reduce "nuisance" DbIo logs
