   Hi @kevinwen2k @amitmiran137, in airbnb we have some use cases like a large 
dashboard shared by different teams with 500+ unique users per week. For 
dashboard with 40+ charts in one dashboard view, the dashboard performance will 
be really bad. If user apply dashboard filters and filter apply to all charts 
in the current view, the perf is even worse that may freeze browser.
   
   I don't think make dashboard show favorite charts only solution will work. 
This problem is more like how to organize large number of charts (or large 
amount of data), simply hide and show inside a single dashboard can't handle it 
completely.
   
   - Tab(s) and nested tabs are supposed to organize data inside dashboard. If 
each tab has  a lot charts and impacts performance, please consider create 
multiple dashboards.
   - another use case is, all users shared a big set of charts, but each user 
only care a small set of charts, and each users' interested charts are not 
overlap. You should consider let user to build their own dashboard, but pick 
charts from the same pool. So that the same chart will be re-used in different 
dashboards. And once the chart is updated, all different dashboard should show 
this change accordingly.
