Move __layouts to their own folder like params

[homerjam]

With the named layout syntax available how about moving the layouts to their own folder and having a reserved layout named 'default'.

Secondary request - find a nicer way to run arbitrary code on every page load for things like auth and setting up a urql that doesn't involve repetition/making a mess in layouts.

This would introduce unnecessary noise in filenames, if you do that you would get a folder structure like:

/products
  [email protected]
  [id]@product.svelte
  [email protected]
  [email protected]

instead of the easier to process

/products
  __layout.svelte
  index.svelte
  [id].svelte
  search.svelte
  request.svelte

and if you get nested layouts this would become even more unwieldly.

[homerjam]

Good point. Is it possible to do this?

/products@product
  index.svelte
  [id].svelte
  search.svelte
  request.svelte

Not currently no.
Don't think there any plans to add it either

They added named layouts recently. I also suggested it in #5037
