[nick1udwig]

Is your feature request related to a problem? Please describe.
Its hard to tell where imports are coming from when you import as

use foo::bar::*
use baz::biz::*

Describe the solution you'd like
Make all imports explicit.

@nick1udwig I support this in the runtime, but I have a hard time not importing * from kinode_process_lib inside apps. What do you think of that? Is it a reasonable exception?

[nick1udwig]

My claim is that it is a better practice in general to have explicit imports. I suppose if you only import * from a single crate it isn't as big of a deal as when you do it from >1 crates, since then you can infer "oh it came from the only crate that is *d". However, you do still lose some traceability in that I can no longer just search that function name and find either its

1. definition
2. use foo::bar::the_func;

which is a loss in traceability.
