At the price it’s hard to go wrong ! I think they’re adding to it in firmware as well, more on why i think that soon.
You could likely do an overlay on the front panel.
Downside for me with the design is figuring out the meaning of the four binary LEDs. It’s a little abstract from looking at the manual.
But using the LEDs rather than a full display helps keep cost down, and it isn’t a show stopper for me.
