# feature:
## In Browser:
- hidden back&forward button in sidebar.
- back and forward is equal with `window.history.back()` `window.history.forward()`
## In Desktop:
- Back and forward can be controlled through the sidebar, cmdk, and shortcut keys.
- back and forward act on the currently **active** view.
- buttons change disable&enable style based on current active view history
# Refactor:
Move app-sidebar and app-container from @affine/component to @affine/core
To support multiple instances, this PR removes some atoms and implements them using the new DI system.
removed atom
- `pageSettingsAtom`
- `currentPageIdAtom`
- `currentModeAtom`
Replace internal CMDK command filtering/sorting logic.
The new implementation includes the following for command scoring:
- categories weights
- highlighted fragments
- original command score value
The new logic should be much cleaner and remove some hacks in the original implementation.
Not sure if this is optimal yet. Could be changed later.
fix https://github.com/toeverything/AFFiNE/issues/5699
after this pr, server will only accept client that have some major version
the client version <0.12 will be rejected by the server, >= 0.12 can receive outdated messages and notify users
LiveData is a reactive data type.
## basic usage
@example
```ts
const livedata = new LiveData(0); // create livedata with initial value
livedata.next(1); // update value
console.log(livedata.value); // get current value
livedata.subscribe(v => { // subscribe to value changes
console.log(v); // 1
});
```
## observable
LiveData is a rxjs observable, you can use rxjs operators.
@example
```ts
new LiveData(0).pipe(
map(v => v + 1),
filter(v => v > 1),
...
)
```
NOTICE: different from normal observable, LiveData will always emit the latest value when you subscribe to it.
## from observable
LiveData can be created from observable or from other livedata.
@example
```ts
const A = LiveData.from(
of(1, 2, 3, 4), // from observable
0 // initial value
);
const B = LiveData.from(
A.pipe(map(v => 'from a ' + v)), // from other livedata
'' // initial value
);
```
NOTICE: LiveData.from will not complete when the observable completes, you can use `spreadComplete` option to change
this behavior.
## Why is it called LiveData
This API is very similar to LiveData in Android, as both are based on Observable, so I named it LiveData.
Use new `transformer` to import onboarding json templates.
The json files are generated via this gist

Not using the all-in-one `ZipTransformer` to import onboarding via a zip file.
1. The main concerns is that we still need to serve the blob resources via CDN to reduce user's blob usage. Otherwise the user will get the onboarding images being uploaded to cloud server every time he creates a new workspace. In this PR we extracted parts of the code from `ZipTransformer` in blocksuite and mute some code for uploading blobs.
2. it maybe not necessary to use zip for loading snapshots.
This PR is a short term solution. whether or not to tune the transformer api design may need further discussions.
