I have hundreds of sessions at my local tracks. When I sort by track, it takes forever to scroll down to the bottom of the list to find Summit Point. It would be super handy to be able to collapse each track's list with a little minus sign and expand them with a plus sign.to expand them. A collapse all button would also be cool, that way you can click that, and then have 8-10 lines for each track, and you can hit the plus sign to expand the track you are looking for.
Using this on a Galaxy S5.
Thanks again, love the app, and recommend it to a bunch of my friends at the track.
