Sometimes you need to correct a typo, complete a half-filled entry, or remove a spammy submission. Both edit and delete are available from the entry modal.
Editing an entry
Click an entry to open it.
Click the pencil Edit button.
Update any field value inline.
Click Save.
Deleting an entry
Open the entry.
Click the trash Delete button.
Confirm in the dialog. The entry is removed permanently.
Caveat
Edits and deletes are immediate and irreversible — there's no undo or trash bin.
