Right now we can only see which company has highest Q and we can only see what Product it is when checking the showcase of the company.
How about changing it to something similar to the animals ranking.
There we can see all animals available.
I would suggest something similar for the Quality.
1 icon with all Q's like we have right now and then links like in the Market with all items and their top level Qualities.
It might be to much to get all companies in the list, so we could make it top 100 levels of each item and maybe even a limit of Q20-50 to even get into the list depending on the stage of the game.
At the start Q won't show up below Q10, after a year you need Q25 and after 2 years you need Q50 to even reach the top list.
Then we can check who has better Q then you do yourself and see how to beat them

It shouldn't be to difficult to create, would it??
