I thought the Playground cache holds all evaluated/used expressions.

But it just caches the current text and if you remove the current text, the cache
file is deleted.

And it does not use just one file, but one for every opened playground with text.
And if you close the playground, without deleting the current text, you ' ll end

up with many (many many) cache files. (and it takes some time opening the
first playground after image start up).

Pressing the little "..." icon shows an unscrollable large list with all the cache entries.

(even duplicate entries).

How about creating just one cache file, and only add used/evaluated expressions
to the cache?
