Yes. It is true that it is easier to see and copy the ini file in portable setup.
This made me think of adding an option where users could choose in which folder they want to save the 5 backups of the ini file.
Also, you probably know that but I wanted to add that, for the record, the AppData folder is hidden by default. If you do not change this setting in Explorer options, you need to enter the full path to get it, for example "C:\Users\username\AppData\Roaming\Quick Access Popup" or the shortcut using an environment variable "%appdata%\Quick Access Popup".
