I'll just recheck on my end if I find again the reason as to why I wasn't willing to go that way last time I checked this param, if I can't recall why LGTM

Thank you for the help on this project, as always. Much appreciated

Sounds good! Take your time checking it out. Let me know if anything comes up and I'll be happy to work on the other options.

Okay, I kinda remember that it was an problem with the rendering of generic types, but I guess it's been since resolved by zensical, because testing it myself locally I didn't see any problem, and it fixed everything, so let's go with your proposal! thanks again :)
