Since I've made that thread, Arturia implemented the install path choice, which is great. But actually, it created another problem for me, installing CAM stuff on an HDD, as opposed to an SDD, isn't a good idea if you like things to load fast, and I only realized this recently.
I now have another request: letting you choose the install path for the plugin AND the install path for presets and samples. I found a way to artificailly have this using mklink commands, but I think next updates won't be without issues.
On a related topic, it would be nice if we could choose which GUI size we want to install, personally, I only use 80% and the rest is basically unused, and it's A LOT of png files. I tried deleting these image folders but it breaks the plugins.
