PMF can display multiple tables in a tabbed view. Usually, the first 2000 rows are displayed (this is configurable).
You can directly edit the cells, and clicking 'Save' will update the database.

The cells have a context-menu for quickly filtering (e.g. SELECT * FROM table WHERE colName1 = colData1 AND colName2 = colData2 ....) data.
The context-menu also lets you edit XML data and display LOB (Large Object) data.
It's also possible to copy and paste rows across databases (provided source and target table have the same columns, of course).

Additional functions:

PMF is intended as a lightweight and intuitive tool for developers and admins. If you have suggestions for improvements, let me know.
