Most likely everybody else that is new like me is doing the same.
It is a typical mistake to conclude from oneself to everybody. When I started with OMV, I also had never seen anything like it and still never had any problems with it. The many confirmations with OMV6 also bothered me. But here votdev has already relented and scaled it back.
When I started I was having a hard time to get the difference between sharedfolder privileges and filesystem permissions / acl. Still I would not say it is a problem everyone has. However, votdev has recognized this potential lack of information for many users and added a info box to tell them. Despite being against explaining things outside of docs initially. You certainly can't accuse him of not accepting criticism, even if he's against something at first. I assume if enough users have problems with disabled Netbios, he will come up with something. Currently, support requests doesn't seem to indicate it.
The rest of your criticism, e.g. of the dashboard widgets, is personal preference. You don't like the current implementation. I don't get it but thats ok. You can decide for yourself if it is so bad for you that you would rather use another operating system.
