It seems that even creating a new Filter Set to get around the “one Filter By option” per Filter Set problem I wrote before, have its own problem.
Let’s say on first Filter Set I have used Filter by: product tags with “type” as its Prefix for URL.
Then if I create a new Filter Set and use Filter by: product tags again, the Prefix for URL will use “type” and cannot be changed just for this specific filter (can only change it on main setting’s URL prefixed which affects every ‘Filter by: product tags’ filter)
Was this intentionally designed this way? Why? This really limits the usage of this filter plugin.
