For me, the issue with the Touch Bar, and with this software is that it misses the reason I want shortcuts in the first place. I don't want another screen with shifting context, I want to rely on muscle memory to execute a task _without_ UI context. I want to interact with graphical context using my main display (touch or otherwise), and I don't want to use a smaller less flexible display for this task.

That said it is a neat technical achievement, and I applaud any effort to improve the HMI.

Exactly. What I'd like to have is a tool that analyzes what I do, and reminds me what shortcuts I can use to be more efficient. It would be awesome to have that on my smartphone screen like the solution on display here.

I would be very happy just to have the shortcut written on the right of the menu option like is was when interfaces were still sane.

But yes, I would like that assistant too.

This is to some extend implemented in Samsung's screen edge feature found on phones with curved screens (although it is not context aware by default):

Maybe this could be a solution?- http://www.martinhajek.com/the-1st-accessory-for-the-oled-ma...

I feel that recognisable and consistent tactile feedback is so important for developing and executing muscle memory. Today on most devices this element is largely overlooked (eg. compare a walkman with physical buttons to an music application on a flat screen surface).

Touch screen devices with vibration hardware have not really addressed the haptic positioning and behaviour of tactile feedback.

All of this to me is a loss of opportunity to exercise an additional "input method".

In the future I expect to see somewhat of a non-flat screen that's able to reposition the height or texture of its area to facilitate the do-not-have-to-look precision requirements of today's on-screen buttons. Somewhat of a 3D holographic surface which you can touch or otherwise feel.

There was a concept like this floating around the internet a couple of years ago.

I guess the more interesting solution is power-user specific: it knows what you're focusing on/working on and shows the list of keyboard shortcuts relevant to your current activity. Debugging? Here are the pause, step, return, etc, shortcuts. Searching for text? Here's help for RegExp...
