How Do I Make Playhead Return To Original Position in PrPro?

So, I've recently switched from Sony Vegas to PrPro for video editing, and there's 3 features I miss from SVPro.

One of which is when I press stop (Space) the Playhead returns to where I started it, NOT from the beginning of the clip or timeline,

but from the spot I started the playback (i.e. I start the playback at 1 minute and 37 seconds, I let it play for about 50 second and I press space, then it returns to 1 minute 37 seconds) How do I enable this in PrPro? I'm using PrPro CC 2015.

The other 2 features I miss would be awesome to have, so IF you know of a way to do this I'd love it.

Why doesn't the audio waveform show when I move the clip with a mouse? It does in SVPro and it helps syncing or matching audio/music up with a clip perfectly with ease and fast, whereas this process is a lot slower and tedious in PrPro. Is there any way I can make the waveform show even when moving audio clips with the mouse?

And WHY can't I implement clips recorded with Nvidia Shadowplay without it going out of sync? That's the main reason I switched to using SVPro (Back in the day I started with PrPro but the sync problem and the task to fix it took way too long, SVPro made the entire process 50 times faster) Is there a fix for this too? I know shadowplay records 60 FPS variable framerate, but can't I get a feature or put on a setting where it takes this into account and DOESN'T de-sync it?

Of course the MAIN subject is the playhead, I really miss this feature, but if any of you know an easy and quick fix for the other 2 I'd love it! (I've not updated PrPro because I don't like setting things up anew, I'm stubborn yes I know - If all of these features are in newer versions please let me know and I'll get those installed ASAP)

Thanks!
