What do you want to see in Hype?
Option for user to define their own keyboard shortcuts.
Have you found a workaround for this problem?
Yes. Use Hype as is, and stop complaining about not having custom shortcuts.
Are there examples of other apps with this feature? Or, have you seen examples of this elsewhere on the web? (Please include a URL)
Photoshop, Animate, and Illustrator all have very robust features to customize these.
For me it's more about the option to reassign existing shortcuts, as well as adding new ones.
At one point I had all timeline-based applications set to use the same shortcuts for things like Insert keyframe, Delete keyframe, show/hide element, lock/unlock selected element, etc. That made for a seamless workflow when switching between multiple applications.
