You're using the Diode CLI clients, it gives direct and raw access to the relay network. If you want to try "Diode Drive" you've to get the download link above that.
Although the username is just an alias to a public key, it is almost unavoidable to have to use one's username (for example to join a Zone). So, we have support for multi-user single-app coming so different profiles can be applied to different zones so you can use "nikolay" for friends & family, and "myprofessionalhandle" for work stuff, and "myincognitohandleN" for other stuff.
I empathize - blockchain's benefits do suffer greatly from the behavior of many practitioners. It is wise to carefully evaluate...
However, doing even certain simple things, like securing time (https://eprint.iacr.org/2019/579.pdf), benefit from hardened consensus. Our background is in high reliability IoT infrastructure, so we got here not by bullchain hype, but by discovering and leveraging certain unique technology benefits that directly contribute to allowing solutions like Diode Drive to exist.
Nothing wrong with using the CLI, but the CLI is a more general purpose tool for exercising / leveraging the Diode Network, while Diode Drive is tailored to file / folder sharing/collaboration/backup. The CLI doesn't yet support all of the file-specific capabilities implemented in Diode Drive.
I am an early adopter and I've tried tens of thousands of products and services during launch. You should put a much bigger effort on the UX. I'm really confused and if I'm confused, the regular folk will just not wanna touch it with a ten-foot pole!
Thanks for the feedback, we 110% agree - a UI update is coming in the next 2 weeks that is a first step. Please shoot us any specific feedback you have! https://t.me/diode_chain
