Navigate presets with arrow keys and prev/next buttons

Today presets are accessed through a combo box. When a Substance has dozens of presets, going to the next preset is a pain: open the combo, scroll the last preset used, select the next one. I'd like to be able to easily move from one preset to another, with keys or previous/next buttons.

Also, after selecting a preset, there is nothing in the user interface show which preset has been selected. At some point we may have forgotten which preset was selected, hence the difficulty to go to the next or previous one.
