yes I agree if the words are too close to each other the shortcuts will be harder to separate from each other compared to a vertical alignment. But I don't think this is going to be a problem. First because a horizontal layout also offers more space. So without having tried it I would assume you would get as many words in the horizontal layout as in the vertical now. Second I don't think readability is so important here since people create their own shortcuts and know their placement by heart. So even if it gets a bit messy it's not that bad.
I could think of three things for improving readability though:
- character limit for the shortcuts
- a small separator symbol before each word (could be just a dot or a line)
- the black bar is actually so wide that maybe even 2 rows could fit in
But I think before it gets way too messy, there should be just a hard limit on how many shortcuts you can have or the typeface should get smaller with larger amounts of shortcuts. That way everyone can decide what's more important to them
Thanks for considering this!
One more wish: it would be great to be able to include the F-keys in the shortcuts. I have a lot of "Actions" assigned to F-Keys that do more complex things I use very often.
