Quick toggle the Dashboard visibility

All, referring to this tread I would like to suggest adding to the panels a function to show/hide, i.e. toggle, the dashboards similar to "custom screen".

I know that both dashboards (subject to setup) and custom screens could be closed by using of "back". This is an option even if "toggle" function seems more convenient to me.

For the use case, please refer to the original thread.

Kindly vote if you find this feasible.
