Yay more notes.
Changing the File Manager (Nautilus to Nemo)
So, I hate the default file manager in Ubuntu. Unity is fine (meh), but the file manager is dumb. Super dumb.
In this article, a dude did a comparison of file managers available for Linux.

Nautilus is the default, but dude liked Nemo (very much a Sea theme going on here).
His instructions for installing Nemo weren’t too useful (old), but these are totally fine.

Long story short:
Keep in mind, this has changed the default. If you search applications, you should 1 or more programs named “Files”. Click on it and see if it start the correct program.
Remember, you still have Nautilus installed, so if you have an icon on the Unity bar for Files, it links to the old program. Start Nemo, pin it, and unpin the old one.
UNFORTUNATELY this has no effect on the File->Open or Save dialogs. Those are rooted in a GTK 2+ vs 3+ issue, which is unclear. Bah.
