I think that your rant on poor product design sums it up nicely. Now that you are wearing the owner/manager hat, everything has to be built to a "price point". Please consider your potential buyers, they are young students or hobbiest powering their new 'duino' something or other and all they want to do is program the damn thing to make their new LCD say "Hello World". So wouldn't you think that an LCD, say 8x2 or 1x16 for both voltage and current display is the best choice.
As I type this there is a 8x2 lcd sitting on the keyboard in front of me, and a 16x2 next to the mouse pad, bought a box full of them from a swapmeet, and since I am trying to teach myself PIC programming, I decided that a cool project would be to make a simple voltmeter that I could plug into my uCurrent! (I already finished my "blinky light" project.) And while I was at it, I was going to make two, so I have one for the EEVBlog dummy load that I plan to build.
Ya, sure, I have five four DMMs but one is at work, one being disassembled/repaired, another is an 400A AC/DC clamp ampmeter, another Wun Hung Lo thats a POS and I dont trust it, and a analog Simpson 260.
Ever thought about doing a Rev 4 uCurrent?
Would I buy one, no LCD, NO!
With an Character LCD, YES! Seven Segment LCD, Maybe...
I will give credit where due, its a novel cost cutting idea, I have done that exact same thing with a device I made years ago for chasing down short circuits in cars, it was the current display in amps using a bargraph, built with a LM3914 and a 25w 1 ohm resistor.
Time to put your Product Design Engineer hat back on....
