This would be helpful since you can only use static queries to create lists in Webview and to have to open database view to refresh a query so you can view it as a list in webview is cumbersome. It would make it easier for database managers to share lists with web-only users.
Looks like it won't be implemented - see explanation: RENXT-I-304 / New idea
Refresh Button on ALL List Types (and wherever else applicable/possible)
Another way around this would be to add more field and filter options when building lists in NXT view so we wouldn't have to use static lists as a starting point when what we really want is dynamic lists.
