What Nostr has to offer now and in the future, it's impossible to make simple client. Look at the NoStrudel. It's cluttered as hell and I stopped using it because of this reason. 

There are good deaktop clients which are simple and clean. 

I don't know what you actually need but the clients like amethyst exist as web apps but the buttons and workflow is different. Underlying tech is the same. 

 

 Obrigado por explicar. Vou tentar algum client desktop durante a semana!
