new Reader DC not comfortable !

with the new DC version the view is not user friendly...

1. f. ex. page size always different, would like to keep it for all documents stable.
2. the toolbox always present, don´t need it regularly

Previous version were better, but getting worse with each update, think of using alternative tools, but in side companies you are forced to keep a tool which makes work life harder than necessary !

I really ask myself who is responsible for the application aspects at ADOBE ?
