This little branch adds an interesting "wow" effect by not blanking frames. You can configure a key

Cosmology can now read and write to files.
It would be nice to register with Cosmology.write a method for exporting a Cosmology to a HTML table.
There are good examples of IO with Cosmology at https://github.com/astropy/astropy/tree/main/astropy/cosmology/io
and documentation at https://docs.astropy.org/en/latest/cosmology/io.html#cosmology-io

I'm thinking the write_html(...) method

In sunpy 3.1 I added the ability to plot a subset of the columns in a GenericTimeseries: https://docs.sunpy.org/en/stable/api/sunpy.timeseries.GenericTimeSeries.html#sunpy.timeseries.GenericTimeSeries.plot

It would be good to roll a similar change out to all the timeseries sources.

We could look into using the diskcache package to cache MAST search operations:

https://pypi.org/project/diskcache/

The package is a disk-based key-value store which makes it easy to specify an expiration time for each entry. This would allow us to e.g. cache search queries for 24 hours, which would significantly speed up searches across different Python processes, whilst largely avoiding
