Most of the Pangolin crew is probably tied up with the PROLight and Sound show in Shanghai right now, and may not be available for a quick response.
As far as your other comments, you might need to spend a bit more time with the software!!
The latest QuickShow beta release definitely supports MIDI key-to-cue assignment, and it works quite well!! 
See my Post # 106 on how to set it up -
You may not be able to right-click a cue and assign a key "at will", but you can easily set up a sequence and rearrange cue pages to give you access to up to 60 individual cues per page, using the key mapping sequence you select. An additional enhancement that should be coming out soon enables the selection of up to 16 individual pages. Once this is setup, you'll have access to any cue, on any of up to 16 pages, on demand, via MIDI.
(Remember - this IS beta, which means "it ain't done yet...
)
It works QUITE well - I tested it linking to Showtime, and using several different software-based MIDI controllers, all using standard General MIDI channel and "note on / note off" controller messages, and everything works fine!
At the very least, with the current beta release, you should have access to a full page of cues (your page choice - use the "direct all notes to current page" option), on demand, using your key sequence.
If that doesn't work - could be you might have a configuration issue, or there might be a programming issue with your particular controller, perhaps? 
If it's the lack of a visual confirmation that is your primary complaint, that's one I definitely don't quite follow -
As mentioned previously, a selected cue is VERY obvious on the QuickShow cue grid, even if isn't active.
Plus -
I could be wrong, but controller "status light" activation sounds very much like an advanced controller feature that requires very specific driver support within the software, or some sort of interface applet running in the background. All the MIDI implementation that I have seen in the Pangolin software (for the QM2000 and FB3) - which is quite robust, by the way - relies almost exclusively on General MIDI standard controller implementation, which maintains compatibility with the widest range of MIDI controllers, and no requirement for controller-specific drivers. Virtually every major control feature and every cue in the Pangolin software can be selected by nothing more than standard "note" and "continuous controller" messages
As far as "knowing" which key selects what cue, the user establishes the key sequence -
after that, the key-to-cue mapping is set until changed by the user, so really knowing the mapping comes from practicing with the hardware and software.
(Just like a keyboardist has to practice to know which key corresponds to which note on a piece of music - only this is easier!)
QuickShow's MIDI implementation works very similarly to that of LivePRO, which is used by some very well-known pros around the world (some who post here).
I think if that particular implementation - or lack of "status" light activation - were a problem that would impact most users, it would have been addressed a long time ago.
Personally, I REALLY don't think the lack of LED "status" activation on a particular brand of MIDI controller means QuickShow only has a "half implemented MIDI control system...
