Flight computer/vario manufacturers are you listening??

Probably not.

The observation from a semi-inside guy is this: Just about everyone (from designer to end user) is willing to "go to the wall" over UI stuff, including audio. The result is that the designers grow a very stiff backbone over this... sometimes to the point of total intransigence. In my current cockpit, I can point to things that are pure brilliance, unusable, awkward, intuitive, broken / inoperative, idiotic, obsolete, "that seemed like a really good idea, but just doesn't work in the cockpit" and innovative / really cool. The designer / developer(s) won't change a goddamned thing except on his own whim.

It's quite frustrating. The big opportunity in sailplane instrumentation is UI.
