Update UI

[j-andrews7]

UI looks pretty dated as it stands. A few quality of life changes would make it look a lot better and improve functionality.

• Change button from the default to something that doesn't look like it's out of DOS.
• Use collapsible sections for the section headers.
• Remove the header disappearing/reappearing. Instead just collapse the section if it has no info found in it.

2785dbf implemented all of this. Sections are collapsed by default, which is slightly annoying, but making them open by default makes it so you have to click them twice to get them to collapse, which also displays a bit of a visual glitch. After the initial click, they work fine.
