Change the default path of Store and Download?

[nkarl]

My workflow on Windows is that I have:

~
|__ .local/
|   |__ bin/
|
...

~/.local/bin/ is where I placed binaries for my terminal shell. It's in my user space so it doesn't require elevated privilege. The same with my java versions. I have them stored at ~/.jdks/.

Can we decouple the default download and install paths to ~/Downloads and ~/.jdks/ instead?
