I've been working in the DataBuilder lately trying to debug and issue and some of the following UI changes could be helpful:

Tables Context Menu

Add "Delete Tables" option

Display a form that has the tables in a list with checkboxes.  Select checkbox next to table to delete/drop.  Press OK button to perform delete action or Cancel to cancel operation.

Table Context Menu

Add "Delete All Indexes" option similar to "Delete All Records" option.

Delete Key

• Make it possible to delete tables by pressing delete key
• Make it possible to delete indexes by pressing delete key
• Make it possible to delete views by pressing delete key
