This modified example will print the preset name when each time you save or change the preset:
<Cabbage>
form caption("Presets") size(370, 280), guiMode("queue"), colour(58, 110, 182), pluginId("MPre")
keyboard bounds(10, 90, 345, 95)
rslider bounds(12, 8, 85, 79), channel("att"), range(0, 1, 0.01), text("Att.")
rslider bounds(98, 8, 85, 79), channel("dec"), range(0, 1, 0.4), text("Dec.")
rslider bounds(184, 8, 85, 79), channel("sus"), range(0, 1, 0.7), text("Sus.")
rslider bounds(270, 8, 85, 79), channel("rel"), range(0, 1, 0.8), text("Rel.")
combobox bounds(74, 190, 100, 25), populate("*.snaps"), channelType("string"), channel("presetName")
filebutton bounds(12, 190, 60, 25), text("Save"), populate("*.snaps", "test"), mode("named preset")
filebutton bounds(12, 220, 60, 25), text("Remove"), populate("*.snaps", "test"), mode("remove preset")
