Automatically collapse "import" block in files.

[MartinSGill]

On larger projects you can end up with 10 or more lines of "import ... ;" statements at the top of a file.

It would be really great if vscode could detect if the there's a huge block of import statements at the top of a file and treat them as a collapsible region, and automatically collapse that region when you open a file.

At it's simplest I would define an "import block" as

1. The only lines above the first "import" statement are comments or empty lines
2. Line matches "^import\b"
3. Line is an empty line
4. Line is a comment
5. The end of the block is the first non-empty, non-comment line that does not match "^import\b"

It might also be worth having a minimum size before imports are treated as a block/region. E.g. 3 or more lines.

Right now folding is purely indentation based. What you are asking is language aware folding.
That's #3422

Reopening to track the TypeScript/JavaScript specific part of this request from #21632

[testerez]

I wonder if it could be achieved by an extension...

[mjbvz]

Depends on microsoft/TypeScript#22419

e628e8e marks TS imports as foldable (you also need to be using a typescript build from master to actually test this)

@aeschli Is there an existing bug tracking auto collapsing FoldingRangeKind.Imports for all languages?

[aeschli]

We have #40338 to think about configuring the initial collapse state.

Thanks @aeschli. Folding of imports is now in vscode with d8e5520

Initial folding state is language independent so I'm assigning this issue over to you now. Let me know if there is any js/ts specific work that needs to be done
