ProffieConfig v1.7.0 brings, along with a couple of neat features like preset injection files and an interface for custom props, the V2 update system, which installs much more like a normal application would be expected to, and is a major structural update.
This release I consider a beta at the moment. If anyone would be willing to take a second and test this and report any issues to me (and lack thereof), I would greatly appreciate it!
