Certainly, more shortcuts can be added, but I won’t add them for “everything”. That would mean adding a shortcut to enable the white balance checkbox and a different one for the split toning checkbox, etc. You can add your own shortcuts for anything in a menu using System Settings and I will add shortcuts for more commands as I go. (It may be counter-intuitive, but some shortcuts are easy to add and some are extremely difficult.). I will also slowly add more commands to the menus to make shortcuts possible to add.
