I know that Njump has some technical points, but they are largely intentional; in fact, if one of the goals is to let the user jump to a complete Nostr experience, there are other goals as well, such as educating (perhaps even subliminally) about a new paradigm.
This includes showing, even if only in passing, some "strange" but necessary concepts such as public key, relays, and having multiple apps to choose from.
I am 100% in favor of a fluid UX, but I don't think babysitting users too much is the way to go; we need to leverage some awareness to promote a more informed use of technology. How is a continuous work in progress, with the necessary trial and error.

On the UX side: granted that hiding the main call to action below a dropdown, requiring 2 clicks (hover brings accessibility problems) where there is plenty of space doesn't seem the inevitable choice, we are talking just about the desktop view here, forgetting than about ~80% users use a smartphone :) And there the dropdown is present, for obvious reasons.

However thank you (and Niel) for the suggestions, I will take them into consideration; there are definitely some elements that can be improved, such as labeling, the date visualization, adding contestual helps, and the localization, of course.
