Inconsistent terminology referring to viewlet in commands

[Tyriar]

#62097

Looking at the commands list we refer to the viewlet as "viewlet", "sidebar" and "sideBar".

I think we lack a clear UI component terminology in the Workbench. Some problems:

• What is a "View"?
• What is a "Viewlet"?
• What's the relationship between "View" and "Viewlet"?
• Does Sidebar contain 5 Views or 5 Viewlets?
• Does Panel contain 5 Views? 5 Viewlets? 5 Panel Views?
• Is terminal a "View"? "Viewlet"?
• Is a tab in terminal a "View"?
• Is everything listed under the view command a "View"?

I hope we can work on some updated illustration for https://code.visualstudio.com/docs/getstarted/userinterface that breaks down the Workbench UI for user understanding.

Here's our general principles:

1. Never expose term viewlet in the UI
2. Everything under the "view" command is actually a view. We just use the term view in general everywhere, which I think is fine

Now taking this into account please let me know where you think we are incosistent and what exact wording would you expect us to change?

Thanks!

View lost meaning if it's the same as "box".

Never expose term viewlet in the UI

You can find a bunch of them as context keys and command names. Should we start deprecate / remove them? For example, explorerViewletVisible and searchViewletVisible.

Context keys and command ids are fine, they are UI visible but are not in the front row visible - let's put it like that. Only advanced users will see them.
Depricating context keys and command ids requires transition of data, backwards compatibility and is a pain. I would vote against that.

Leaving this issue up to you if you are very passionate about changing some names, though I would first bring it up in the UX call.

What I want is tracked in microsoft/vscode-docs#1842, so maybe @Tyriar can clarify what changes he wants.

I was just bringing attention to the inconsistencies
