I can set this up to be quite useful on my iPad. But the settings then carry over onto the iMac (desktop) where they are not optimal.
I can set this up to quite useful on my iMac. It would be nice to be able to toggle between the sets of settings but with the other programming demands on this site I don't expect that to have a significant priority.
Play around with the panel settings and toggle stuff on and off. Move the panels around. You can end up with very useful things but as each of us finds different screens more or less important, you will have to experiment. (Sorry no quick fix. But HOPE.)
