Hiding/unhiding groups

Why is it that I can mass hide/unhide and that works fine, but when I'm trying to unhide a group of objects if I unhide just the group object that doesn't unhide the individual objects, I have to go in and unhide each item? Seems like a bug.

This timeline quirk is a little hard to explain, but I'll take a shot at it anyways. I have a slide (actually lots of slides) with LOTS of objects (30+) on the base layer timeline, which are set to fade in/out to make room on the stage for the next section of content. The length of the timeline also happens to be very long (2-4 minutes). When trying to isolate objects for editing purposes and you finally find the object (or grouping of objects) that you need to edit, you make the edit, but then the timeline refreshes back to the top and beginning after changes to objects are made forcing you to go find that grouping of objects on the timeline again should you need to continue working with them. This adds a lot of time to the editing process.

Btw—It wasn't my choice to develop slides where everything lives on the base layer's timeline because looking at the slide with all objects turned on is pretty scary.

My two requests from this is let me unhide all objects in a group by unhiding the group object and have the timeline stay on the objects being edited until I move it.
