I have proposition with some usefull options for tables to add into popup menu:
shrink space (10g)
deallocate unused ( now this option is in object/storage menu, i think this should be moved into table popup)
enable/disable all triggers
enable/disable all constraints
rebuild all indexes (for partition/subpartition - also rebuild all unusable local indexes)
I think this options could be simply added , then sqlnav functionality could be improved …
Think about it!
