Thanks very much for the response.
It's good to hear that someone else thinks at least a little similarly to me regarding the UI and clear as mud info displayed.
It's disheartening to begin learning that the developers haven't put a huge amount of thought into the overall user experience (I was hoping my issues were from me just being dumb initially). Don't get me wrong, I think Sia is great and a lot of good work has been done in a short time frame, but ease of use is very important when attracting and retaining new customers.
It would be nice to get a response from a known dev to confirm that the problems are understood and likely to be addressed. Is there a more prominent place I should post this?
I've invested a reasonable amount into this technology now because it's genuinely such a brilliant idea. It would be fantastic to see Sia become a world standard for safe secure cloud storage. Their success will be measured by how much the devs listen to end user gripes and ideas for improving the user experience.
