Hi covid19cellatlas portal maintainers (cc Kerstin and Martin), I noticed that the 'Healthy donors' and 'Patient donors' buttons changed on the covid19cellatlas.org portal and were placed in the top right of the screen in blue color on a faint blue background. It took me quite a while to figure out how to access the datasets because of this. I was wondering if this is done deliberately, and whether it could be considered to make the buttons to reach the actual data more clearly visible again? I'm afraid that this would otherwise hamper the accessibility and usefulness of this portal and our datasets. Many thanks and with best wishes, Rik Lindeboom
