As has been said above though for various reasons it’s easy because of the interface to accidentally delete. It’s about accidentally deleting or someone else deleting.
As has also been said above, its functionality existing customers of Virgin would expect with older boxes and its functionality that people migrating from Sky would expect. It must have been a conscious design decision not to implement it in the 360 and that makes no sense. At least make it an option to set in preferences then everyone can have their choice. Seems simple.
Obviously we all try not to delete things we want to keep - that’s fairly obvious and doesn’t need saying, but things happen.
