Congratulations on the tool. I find it very very useful.
I recently discovered a huge list of HiPS maps produced by the Centre de Donnees Astronomiques from Strasbourg (https://aladin.u-strasbg.fr/hips/list) and I wondered whether it would be possible to load any of those maps in ESASky by providing the URL of the HiPS, as listed in the website or in any other even easier way. That would allow a lot more discoveries to be made using those maps, which currently only can be seen in Aladin Desktop I think.
