I sent Feedback via the gear icon. I mentioned the tons of posts from users who also find the Modern View reports terrible (with no user preferring the Modern View) and that the moderators are saying the developers don't read the message boards and they won't let the developers know about the chatter on the message boards.
I specifically mentioned in my feedback that Modern View won't allow for the same level of customizing that the Classic View does. In Modern View, when I try to change the columns, some columns have their box checked even though they don't show up on the report; if I try to check a box to add a column, I get an error message about not being allowed to exceed 20 columns (even though the report only shows 10 columns).
