The next dac, May will have indicator LED's for sampling rate etc.
but the Spring Display has had some complaining about the dimming function to not work for the firs 5-6 clicks... here's the kicker. It's working in fact, but our eyes are unable to see the brightness levels of the first 5-6 values... We are fixing this with a new firmware update and all new spring dacs will ship with this update. So the first click will start to dim the diplay where the human eye can detect this level.
Anyhow, the display will get no other updates, or will never have support for input labeling. there simply isn't enough characters to do anything like this. So would be pointless. Yet we have future products coming I can't discuss on headfi, but will elsewhere. but the near future will be so very exciting!

OK, possibly no room for more characters. HOWEVER, it is possible to change the label codes to provide more information, as long as we don't exceed the maximum number of characters available in the display (six?):
For example; instead of "DSD256", it could be shown "COA256".
"64", "128", "256" and "512" can ONLY mean in this context DSD, so it's not necessary to show "DSD" characters as they are implicit (although many users .may like seeing "DSD" displayed)
Similar can be done for non-dsd formats. For example "192K" can be replaced with "COA192" (no need to show that "K" either), and "44.1K" with "CO44.1". So the simpler solution is use less characters to display resolution info and use the extra available characters to put info about the source.
A simpler mod: change how one of the buttons operate, so that user can select whether to watch the Resolution of the sSource. For example, pressing "Display " and "Source" at same time will toggle between displaying the resolution and the source.
An even simpler (and less useful if used without the above mod): pressing "source" just once will cycle through all sources, BUT beginning with the same source already selected, so that if we press "source" just once, we can see what source is active at the moment without changing it. With current firmware, if we want to know what source is active, we have to cycle through all available sources.
For me not been able to easily know what source I'm using is a BIG usability design mistake/omission in a device with so few options. If that's not corrected in a firmware upgrade... well that will tell me a lot about the brand.
One question: where can I contact "Holo Audio" customer service directly? Is that even possible or do I have to post on forums for that?
I'm insisting on the "source info" issue now because I have a feeling that not many firmware updates will come out for the HOLO dac ("time will tell", as another brand says) so it's probably "now or never" for these (small) changes to happen.
