I really like the idea of #deltachat but I never tried it until now.
It just seemed sooo uninteresting. Why? Because of the graphical and #UI branding.

I'm not even a huge UI fan, I use CLI apps 90% of the time. But the mundane and gray logo, the gray UI, every graphical element of it seems so uninteresting.
The screenshots look like they are from 2010s.

I think upping their design game will really boost users.
Delta is a unique idea on the backend, give users a unique experience in the frontend too.
