I thought I was being more elegant by starting a project at the very beginning instead of my old leaving four blank measures at the beginning habit. I have a midi drum track so I don't need the metronome while the song plays. I just need the metronome for the count in. This is not an option, doh! (would be nice to have a count in during playback as well as recording for rehearsal purposes - this is not an option either, doh!) So I realized I will have to slide the whole project over at least one measure to allow for a count in measure. So why is it that when I slide the whole project over, the markers and time changes and meter changes DON'T slide? Am I missing an option somewhere? Also when trying to insert four measures in the middle of the song by pasting four measures of midi drums (session drummer) and clicking the "slide material over to make room" option, the material would not slide over no matter what I checked or clicked. Does this feature only work with audio, and not midi?
Thanks!

P.S. I was attempting the slide and also the paste in piano roll view if it matters...

If you have Count-in enabled, you should hear it regardless of whether the metronome is enabled for recording, but it might depend on your interface driver - possibly you need to have a track with input monitoring enabled to keep your interface 'awake' when the transport isn't running, and/or make sure you have 'Always Stream Audio Through FX' enabled in preferences.
 
IIRC Project > Insert > Time/Measures will move meter/tempo changes along with track content, but not markers. Slide over to Make Room is only applicable to pasting, but it has long-standing issues (see the ReadMe), and should not be used.
 
EDIT: I just double-checked... even with 'Always Stream Audio Through FX' disabled, and no Audio or Synth tracks in a new project, the count-in is audible with just a MIDI track armed.

To clarify, I do hear the metronome. In my fantasy world I would have the metronome only audible for the count in then go silent as my first track is drums and I don't need to hear the metronome over the drum track. I will definitely go back to my four blank measures at the beginning habit and just include a count in click in the drum part. I guess that was more of a suggestion than a question. fwiw only when recording does the metronome give you a customizable "count-in" BEFORE the timeline starts scrolling. The metronome will sound during playback if that option is ticked but a "count-in" does not occur if not recording.
 Thanks for the quick response! I'm new here but plan to hang out more and ask and hopefully answer some questions.

Metronome count in, then out would be great - workaround is just record x number of hi-hat at the beginning. 

There is a "pre-roll" setting that allows you to set this. It's under Project/Metronome. It's available for recording as well as playback.
 
Regardless, I personally think it's a good idea to have a few empty bars at the beginning of a project. I wasn't sure if you're still interested in the metronome pre-roll since your post is mostly about adding bars to a project and sliding stuff over. That topic would be best covered in another thread (or change the title).

You guys are confusing me, now. 
 
There's a box in Metronome preferences called 'Record Count-in' (not 'pre-roll') where you can specify the number of measures or beats of count-in. As the name implies, it's applicable only to recording. There is no count-in capability for playback, so a track needs to be armed, and you need to start the transport with 'R' to get the count-in, but the metronome does not need to be enabled to sound during recording.
 
In this scenario you should hear the count-in, and then nothing once the transport starts rolling.

Oh oops sorry, there is a tick-box "playback" there so I assumed it was for the count in but that's just for the metronome in general of course. 

Yeah, the layout is a little unclear/misleading. But I'm still curious that it seems to OP is saying he doesn't hear a count-in unless the 'nome is enabled for recording; that shouldn't be necessary.

I, too, have sometimes wished I could have just the count in for times when I want to record something that doesn't follow a click track but has several tracks should start together.
