Searching for items sharing specific parent(s)
I "miss" the ability to search for certain items sharing a specific parent (on any level -- that parent could be several level up or at various levels for any item, so itemParent or itemGParent wouldn't work or only partially).
Why would that be extremely useful ? 2 examples:
- it wouldn't be necessary to recursively tag/mark all items and their subs in a tree to know if they've been classified under a parent or not (and then filter for that tag/mark)
- one could find items related to certain topics without having to tag them in advance.
Parents used in that way add richness to how the context in which an item is found can be used.
