The need to start a chat for a model that is not currently downloaded in order to initiate a download confused me for a minute the first time I tried it out. A more intuitive approach (which is the first thing I tried to do before I figured it out) might be to make the download icons in the model list clickable, to initiate a download. Then you could display a download progress bar in the list, and when models have been downloaded show a little "info" icon that is also clickable to display the model card, surface other model specific options, and enable deletion. Love the new UI, kudos!
