I frequently need to calculate aspect ratios and dimensions when resizing images, so I wrote a ratio calculator plugin for Alfred to make the calculation as efficient as possible.
It works by reading a simplified ratio equation syntax in the form of a b c d where a, b, c, and d represent the numerators and denominators in an a/b=c/d ratio equation. Any non-number character (like x or n or ? or whatever you like) can be used to represent the missing number.
E.g., to get the missing number in the ratio 2/4=?/10, you can type as 2 4 ? 10 and Alfred will return 5, ready to be copied to the clipboard.
I'd say that it's extremely unlikely that Alfred will gain built-in support for Edge unless Edge provides an official API for apps like Alfred to read its bookmarks.
You would probably be better served with a workflow instead. Depending on how Chromium-like it is, a workflow like this one might be able to read its bookmarks.
