2 questions from a confused upgrader

Just upgraded my S4 MK1 after idk how long, (10 years or more?) and a few things are different in the new Traktor Pro 3 that I would like to see if I could get back to the way I am used to. This is mostly related to the browser.

First thing is when I am in the browser, I would like the preview play button to be a toggle instead of a press and release behavior. I am used to the old way where if I pressed the rotary selector once it would play the track and then I could scroll through the track and then press it again to stop.

Second thing is loading a track into a deck behavior. I would like it to act as it used to where you can load a track by pressing the corresponding CUE button above each tracks fader on the mixer. The new way seems a little clunky to me and if its possible I would love to have that feature returned via mappings or something else. Obviously this would keep the cue buttons working as normal when the library browser is closed.

Thanks in advance!
