Basically, it is just easier to manage and filter through when it's more compartmentalized in proper categories.

There is a much bigger reason, however, as to why v0.1.9 and likely verisons above it will have to be their own distinct section. This is primarily because, as of now, you can only ever download the most up to date version of Juice Galaxy, making previous runs impossible for others to run unless someone can pass them the files. (which I do not endorse, and may likely go against the wishes of Fishlicka, the developer)

The other reason is because v0.1.9 not only adds in a new boss, but also adds in a mechanic known as "burst armor" which makes bosses signficantly hader to one-shot. They no longer take massive damage from the attacks that used to guarantee kills.

These differences are so extreme that it wouldn't be fair to put v0.1.9 and future runs in the same ball park with older versions. This basically affects every single category.
