# 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
using a [babel plugin](https://gist.github.com/pengx17/49e24ae8a5a609bdaff122ee8c679d1c) to transform all var(--affine-xxx) to cssVar
Some issues:
- tried ast-grep but it seems to be not easy to add imports conditionally
- current work does not work well with ts with types because babel will strip them out
