Would be very much appreciated if you could update the card accordingly. There currently hardly is an alternative, so it would be a 'big deal' if we could no longer use our heavily decluttered Dashboards...

thanks for considering

That has nothing to do with this topic. Which is about Polymer.

Also, I'll close this, as decluttering seems to not use Polymer and won't be impacted .
