It would be awesome to have “master” views from which others can be derived/scoped, a.k.a. sub-views based on other views!
A use-case of my own:
I have a highly customized view I use all the time, it has lots various filters, groupings, hidden fields, sorts, …
Sometimes I need to filter this view by an specific requirement (ex. a time span).
Currently I have a duplicated view of the original with the added filter.
Nevertheless, if I change something in my original view I have to remember to change it in the sub-view as well.
