### Description

I used KV locally in the project https://github.com/sgohlke/deno-kv-test and it was easy to use it within Deno Deploy. I added the project from the repository and KV worked out of the box as I would have expected it. In the second project it also worked fine.

I stored a JSON object in both cases. While I was able to see the full object in the first one in the second the entry was to long to display so "..." appeared to show the rest in a popup/overlay. I think this might be difficult to read if the object gets bigger, I would prefer some "view value" functionality to display the value (e.g. in a new mask or text area).

It is possible to use KV.list to iterate through the entries but I think it would be nice to have a function like "getAll" to get all entries. Example/Use case: Use `KV.get(['products', id])` to return specific product, use `KV.getAll(['products']).map(entry => entry.value)` to return all products.

Potential new features:

- Database "manager" to perform CRUD operations (or reset functionality described in https://github.com/denoland/deploy_feedback/issues/378 to delete test values)
- Extend input key search to be able to query data (e.g. get all products with category='clothing')
- KV function like KV.incr() to increment a value/number (e.g. increase user counter, increase "thank you" counter by 1).
