Question

In Edit view the ability to quickly expand or collapse tracks with a little button. Currently you have to drag the bottom up or down to resize which is good to customize the size but many other programs such as Sonar and Vegas have this ability

Answer 1

I'm pretty sure this functionality is already there without a button- Have you tried holding CMD or CNTRL and using the mouse wheel while the cursor is over the arrange area? This is how I very quickly minimize or expand all the tracks. At least on my system I can hold CMD, flick the mouse wheel, and make everything tiny. Also ALT + Z gives you a full view of the song which shrinks all the track heights.

Answer 2

Create a folder track and group the tracks. open and close the folder to expand or collapse

Answer 3

I had the same hair pulling experience but finally found the correct answer. I am not sure if you have already what you are looking for but here goes anyway.

In your track list on the left side at the bottom, There is a row of icons for Mute, Solo, Activate All Inserts, and Track View. If you click on the small disclosure icon you can set the standard view for your song. In the image below yousee the world "Tiny" at the bottom, this is where  you change the view.
