Standard Advanced Editing Features

I don’t believe any of these features are currently implemented, so if so perhaps someone here could inform me. But first it would be fantastic to be capable of making a time selection and then cutting that selected piece of audio out of tracks, then simultaneously sliding the tracks on the right over to the left? I know I can use CMD+Shift+d on Cubase when the range tool is selected, or use the ripple editing feature on Reaper, and so this seems to be a pretty standard feature within other DAW’s and It would vastly improve the editing workflow on mobile. The other two big things would be either the ability to alter/add macros, or the implementation of a keyboard shortcut to open the mixer, and a keyboard shortcut to switch over to the “select” tool. These are just small things but they are repetitive tasks when editing podcasts that make it very difficult to embrace a full shift to my iPad, which I strongly desire to do in the next few years. Any advice would be appreciated!
