In Bloom, it is far too easy to entirely delete a node property when editing its value. The bin option is too destructive. Edits have a 'Confirm Edit' button if the 'Edit' button has been used. But if one uses the pencil to edit and then hits the bin rather than the tick (which is very easy to do), one loses the entire property and cannot repopulate the existing value. No 'Confirm?' step is offered even. This one thing makes the interface unusable for my users editing the contents of node (property) data.
