# Roadmap
This is a summary for thenew fatures of the major releases and a collection of ideas.
This list indicates only the current intention and can be changed.
## v8
Planned to November/December 2020
- Create an `lv_components` repository for compley widgets
- It makes the core LVGL leaner
- In `lv_components` we can have a lot and specific widgets
- Good place for contribution
- New scrolling:
- See [feat/new-scroll](https://github.com/lvgl/lvgl/tree/feat/new-scroll) branch and [#1614](https://github.com/lvgl/lvgl/issues/1614)) issue.
- Remove `lv_page` and support scrolling on `lv_obj`
- Support "elastic" scrolling when scrolled in
- Support scroll chaining among any objects types (not only `lv_pages`s)
- Remove `lv_drag`. Similar effect can be achieved by setting the position in `LV_EVENT_PRESSING`
- Add snapping
- Add snap stop to scroll max 1 snap point
- Already working
