Context

Apps want undo/redo.

import { openLix, undo, redo } from "@lix-js/sdk";

const lix = await openLix({});

await undo({ lix });
// or with a specific number of steps
await undo({ lix, steps: 3 });

await redo({ lix });

Undo/redo will be postponed.

The implementation requires more exploration. Questions that emerged:

should undo/redo by version scoped or global?

Yes. It's like switching a file.

How do we undo a transaction aka N commits (per version) in the same step?

We need to add a commit.transaction_id. Then we can group commits by transaction and make one undo.

Stack can be kv or entity

We can model an undo/redo stack as key value or entity with dedicated table. Both works. KV Is prob easier
