Can the address bar add fuzzy filtering function

Not exactly what you wanted but I adapted Fuzzy_Alias to create a FAYT fuzzy search for the recent files collection created by @ByTim RecentFilesLog - Record recent opened files into Collections. The benefit of this is that you don't have to navigate to a new directory to find what you are looking for. You can probably adapt it to your purposes if you want to add folder logging etc.

Note that if your collection has a name other than (RecentFiles), you would need to adjust the script accordingly.
