ArcGIS Hub has the option to add a gallery in which you can show your datasets, sites or apps to the public. In our hub we use it for sharing our apps. Recently the gallery has undergone some change. One of the changes is that the gallery cards are made responsive to the container box. In our hub this caused problems with the app-thumbnails and text position. Furthermore, different app-card sizes suggest a difference in importance of the apps, which is not the case.
Maybe for some the responsiveness of cards is a welcome change, for us it's not. Therefore I would suggest to make the responsiveness optional instead of the only option. Something that be turned off when not needed.
