Feature request: Use more appropriate indicators for Trail/Grid/Juggl view

[oqipoDev]

Is your feature request related to a problem? Please describe. I've seen two main problems with the use of some indicators, mostly in the in-note view.

Describe the solution you'd like

• For the trail view, → is used, but seems to me like that's a navigation glyph
  • › or > are more commonly used to communicate hierarchical relationships (see Windows Explorer, Google Drive, etc.)
• In the next-prev view, putting prev and next is clunky, unappealing, and just all kinds of wrong in other languages, especially in long-ish titles
  • ← and → seem more appropriate for this use

Describe alternatives you've considered I've actually made a theme with these considerations in mind. Pictured in the section below.

Additional context This is a side-by-side view of the modified CSS. Pay attention to the symbology. Don't mind the theming.

Hey, a couple of points:

1. I'm rebuilding the plugin from scratch, and don't intend to implement the Trail view. The Grid view shows the same info.
2. The prev and next fields can be called whatever you want, so you can change the hierarchy field as you see fit
