I would keep them in no show. Create captures to show them depending on the set of FTA that you want to show common to one type of geometry in your model. It's my preference and a nice way to keep the model clean. Sometimes I'll show them, but I won't have the annotation follow the camera or anything like that as it will clutter up the model look. I lock them to planes & keep them small and oriented in a way that is logical and dressed out.
Create a capture that has All Annotations, Then a few Captures showing only certain annotations at a time & views that are appropriate and clean for those annotations, then create a No Annotation or Engineering Only Capture that you keep the part saved in.
