Similar to What's the right terminology for Unity's UI elements?, what is the terminology for the various elements in GNOME Desktop? In particular,
- Is there a "HUD"?
- What's the name of the "Type to search" field and ensuing window? The Visual overview of GNOME page says that "Dash" is something else.
- Bonus question: why didn't GNOME use standard terms like "taskbar"?
As explained at GNOME Shell - Wikipedia, according to Projects/GnomeShell/Design - GNOME Wiki! the main desktop design components are:
Here's an illustration from Wikipedia:
As of Gnome 3.28.2, the bottom left corner of the screen, below the dash, in place of an Indicators tray, have a "Show Applications" grid button which leads to the applications overview.
Good question. It's nice to use the canonical names when searching for or describing desired behaviors, or reporting bugs.
