If many test cases have been added or imported, please add the ability to delete all or multiple test cases.  If each test case had a check box, with ability to check or uncheck all, or check/uncheck all in a Group, then delete all checked test cases.  This may be useful if say 70 or more test cases (exported from Bonnie) can be batch imported, but user wants to revise the import batch/bundles outside MADiE.  It is possible that Bonnie export (zip file) can be unzipped, edited in another tool or command line commands, then re-zipped and imported into MADiE.
