Hopefully with the Global Filter on Dashboards, this is now solved. Do let us know if have any other feedback!

KE We are also working on reintroducing widget zoom mode - so you can click on a widget to expand to fullscreen (with more options) and easily go to Explore Tool from there.

Hi Ke! You could use the explore tool to get more information on retention, but at the moment it only has the option to apply global filters, and we are working towards it supporting splits.

If you'd like to look at retention, the best choice would be to use the legacy tool, sorry again for the inconveniences!
