Improve History Page Speed

[sim-san]

Hi,
the history page is slow and not really interactive.
Currently, there are two new custom integration that tries to create a smooth interactive experience to view the history of your entities.
This is achieved by:

The card uses asynchronous stream caching and adaptive data decimation to hide the high latency of HA's history database accesses and tries to make it into a smooth interactive experience.

• history-explorer-card
• lovelace-plotly-graph-card

Is it possible to use these technologies also in the offical history Page ?

Or use https://github.com/leeoniya/uPlot as mentioned here #11251

Is there a plan to work on the History Page Speed ?

Not reloading the entire data set that is requested upon a selection update would help massively.
With the (Awesome) addition of selecting multiple entities to show in the history tab, when adding / removing an entity it seems that the entire dataset is updated where a partial update would suffice.
