Small suggestion for new u-he MIDI learn update

[jackson881]

I think the new way of doing MIDI learn in the latest updates is fantastic. However, I think it would be even better if you could superimpose the current learned MIDI CC number over each control instead of having them all be blank. The MIDI Table is great and helpful, but it would be much easier to be able to see the current CC for each parameter without always having to switch tabs.
