Having lots of problems with Blueprint context menus in 4.5-preview

Having to turn an experimental feature on and off everytime you want to use a castto seems like it would hurt productivity more than just living with broken context sensitive search (a checkbox 1 inch away vs. 1 2 menus and a window away …)
Maybe that’s just me though, in any event this has to be one of more frustrating things going, this and cursor jumping off of spinners lol.
