the grouping definition could be a user driven file, either one master file .. or single files per machine, if the user could generate a file with the order or paramaters, perhaps it might possible to rearrange groups, or parameters of machines, where a user might user certain parameters almost always and some parameters almost never - buze could load the parameter order as defined by the user. Also it wouldnt hurt to have the Preset option as a dropdown using some keyboard command

you might notice +mode and +glide are ungrouped, and the lines are there as a quick indicator of which parameter u are going to be tweaking, before you even look at the statusbar for confirmation
