Hi,

i would like to have some enhancement for NamedRanges:

NamedRanges are an unsorted list. IMHO it will make sense to add listeners
(for example: elementInserted, elementRemoved, elementChanged) to the 
container, so one gets informed if he has to update a sorted list, for example...

To avoid to many listener calls i would suggest to add methods, where one
can add/remove multiple namedranges too ... 

Further on I am thinking about filter options for the NamedRanges, 
for example:

- filter all ranges defined on a sheet
- filter named ranges, e.g. name with startsWith() ...
- filter case sensitive

This could work for Label/Datbase Ranges too ...

best regards

Oliver
