Not sure if it would be clever to allow deletion of a multitrack record. If the recording media is a HDD (not flashdrive) you will encounter defragmentation afterwards with further recordings, potentially leading to dropouts (no matter if deletion is done on the desk or computer). (…and do not even think about defragmenting a HDD used for multitrack recordings either, tracks may no longer playback well)
Naming recordings before arming would be welcome, though.
