I believe that a better design would benefit the adoption of the app. My experience is that because the website design looks not very modern to me (e.g. the outdated devices). I was actually very surprised by the quality of the app and its design as compared to e.g. standard notes, whose website has more professional look by me. I believe even a template would do the job.
Yes I’d definitely like to redesign it eventually, as I agree it doesn’t present the app in a good way.
