Card: will accept subview path (or card will display subview).

[SynoUser-NL]

Hi all,

There are a lot of Lovelace\Dashboard addons available in HACS, like for instance the Tabbed Card or the Swipe Card. These custom cards allow the use of other (native and\or custom) cards within their configurations.

The main problem I see with most of these cards-within-a-card setups is that configuration has to be done by editing the card's yaml code, which is mostly done by copying yaml code from another existing dashboard. This makes maintaining dashboard code a chore and prone to errors.

I would like to propose a change to HA's frontend code so that any card entity can also be a dashboard subview (by path).

With this change, any custom card yaml configuration would require only minimal entries (cards only pointing to the subview path), while its displayed (true) content can now be editted fully by using the dashboard GUI.

While I do know my way around basic coding, I am not a HA developer and don't know if this proposal is even technically feasible. Should it not be, an alternative may be to have a new card that can display a dashboard subview. Which may even be more flexible..

Imho, either of these options would make dashboard creation much easier and simpler (especially for novice users), as well as make the entire dashboard config more transparent.

Hope I have explained this well enough for others to see the potential as well and to vote for this.
Very best wishes, DenW
