The control panel when you are inside a specific form is a bit small and can be unwieldy when you have more than a few records. It's easy to accidentally select a record, then scroll down (out of view of the accidentally-selected record) and select another. It would be helpful to see a count of the records, or the IDs, that are selected in the window where you have to type in DELETE to be sure you have not unintentionally selected more than you wanted to delete.
