Currently in ESASky we provide access to XMM-Newton RGS spectra and Chandra HETG and LETG spectra:
We are currently in communication with the Chandra mission specialists and the XMM-Newton mission specialists and plan to include further Chandra spectral products (including HRC and ACIS spectra if possible) and in the near future to include XMM-Newton EPIC spectral products in ESASky.
If you have any further details on what products you particularly need please let us know.

In order to load the publications information in the lower panel (and to be able to filter a column), you are already selecting just one object. If ESASky then modifies the number of hats in the display, it will only be 1: the 1 object you selected.
Perhaps what ESASky needs is that the user can chose to load the publications from all the objects highlighted, by academic hats, in the field, and then filter on these? Then an update on the number of academic hats displayed would make sense. However, please note that currently ESASky has a limit of 3000 on the number of papers that can be displayed and sorted in the results table.
Many thanks for your feedback. We've put this request in our backlog and we will coordinate this request with the Herschel archive specialists to find a solution. We'll let you know when it has been implemented.

Great feedback, we've added it to our backlog and will let you know when it's implemented!
Thanks for the feedback. We're looking into this (it's a complicated set up to test!) and will get back to you after the holiday period.
Would you for example like to be able to minimise and maximise the menu of icons? Please send a screenshot of the issue if I haven't understood it correctly.
Many thanks for feedback. We've had similar requests to add a scale and / or a grid and we'll therefor increase the priority of this in our backlog.
If I understand correctly your last sentence, you can take a screenshot of ESASky using the screenshot icon, which removes the menus and data panels but keeps the footprints / sources / background image etc.
Many thanks, we'll add your suggestion to our backlog!
Before we add any new ESA mission data
we consult and validate with the mission. In the case of the Gaia
catalogue, it was decided by the Gaia mission that the best approach is
to provide the coordinates in the same epoch as the catalogue: exactly
the same as what is provided by the ESA Gaia archive. The issue here is
that not everything in ESASky is in epoch 2000. The background images
(HiPS) are in the epoch of the observations. The same with most
catalogues. You can move these images to J2000 only if you know the
proper motions and these are known only to Hipparcos and Gaia objects.
Also there are a few hundred million Gaia DR2 sources which do not have
proper motions therefore we cannot propagate them to epoch 2000 and we
have the problem of either not showing them on the sky or mixing sources
on the sky from the Gaia catalogue with epoch 2015.5 and epoch 2000.
most cases the proper motions in the epoch range 2000 to 2015.5 are so
small that this is not relevant (you can see this by having to zoom in
on an object until a solid line appears). The dotted lines are showing a
representation of the proper motion but do *not* represent the precise movement. Please see the lower part of this section for more information: https://www.cosmos.esa.int/web/esdc/esasky-interface#datapanel
If you are looking in a region with sources of high proper motion, the Gaia archive provides detailed information on how to propagate the coordinates to your desired epoch (under section ADQL syntax -> Epoch Propagation): http://gea.esac.esa.int/archive-help/index.html
I hope this all helps and answers your questions.
Thank you for the feedback. We are working on automatically updating the HiPS and MOCS for all missions in operation. Once this is completed, ESASky will always have the updated MOCS.
We will let you know when this is impletmented.
