This is a summary for planned new features and a collection of ideas. This list indicates only the current intention and it can be changed.
- [x] Unit testing (gtest?). See #1658 - [ ] Benchmarking (gem5 or qemu?). See #1660 - [ ] lv_snapshot: buffer a widget and all of its children into an image. The source widget can be on a different screen too. The resulting image can be transformed. - [ ] High level GPU support. See #2058
- [x] merge MicroPython examples - [x] add a "Try out yourself" button to the Micropython examples
- [ ] CPP binding - [ ] Plugins. In v8 core and extra widgets are separated. With the new flexible events, the behavior of the widgets can be modified in a modular way. E.g. a plugin to add faded area to a line chart (as in the widgets demo)
- [x] Display the Micropytohn examples too. - [x] Add a link to the example C and py files - [x] List of all examples on a page. All in iframes grouped by category (e.g. flex, style, button)
- [ ] Add automatic rebuild to get binary directly. Similarly to [STM32F746 project](https://github.com/lvgl/lv_port_stm32f746_disco#try-it-with-just-a-few-clicks). - [ ] Implement release scripts. I've added a basic specification [here](https://github.com/lvgl/lvgl/tree/master/scripts/release), but we should discuss it. - [ ] Unit test for the core widgets
- [ ] Optimize line and circle drawing and masking - [ ] Handle stride. See [#1858](https://github.com/lvgl/lvgl/issues/1858) - [ ] Support LV_STATE_HOVERED
- Reconsider color format management for run time color format setting, and custom color format usage. (Also [RGB888](https://github.com/lvgl/lvgl/issues/1722)) - Make gradients more versatile - Make image transformations more versatile - Switch to RGBA colors in styles - Consider direct binary font format support - Simplify `group`s. Discussion is [here](https://forum.lvgl.io/t/lv-group-tabindex/2927/3). - Use [generate-changelog](https://github.com/lob/generate-changelog) to automatically generate changelog - lv_mem_alloc_aligned(size, align) - Text node. See [#1701](https://github.com/lvgl/lvgl/issues/1701#issuecomment-699479408) - CPP binding. See [Forum](https://forum.lvgl.io/t/is-it-possible-to-officially-support-optional-cpp-api/2736) - Optimize font decompression - Need coverage report for tests - Need static analyze (via coverity.io or somehing else) - Support dot_begin and dot_middle long modes for labels - Add new label alignment modes. [#1656](https://github.com/lvgl/lvgl/issues/1656) - Support larger images: [#1892](https://github.com/lvgl/lvgl/issues/1892) ---
- Create an `extra` folder for complex widgets - It makes the core LVGL leaner - In `extra` we can have a lot and specific widgets - Good place for contributions - 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 - New layouts: - See [#1615](https://github.com/lvgl/lvgl/issues/1615) issue - [CSS Grid](https://css-tricks.com/snippets/css/a-guide-to-grid/)-like layout support - [CSS Flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/)-like layout support - Remove `lv_cont` and support layouts on `lv_obj` - Simplified File system interface ([feat/new_fs_api](https://github.com/lvgl/lvgl/tree/feat/new-fs-api) branch) to make porting easier - Work in progress - Remove the align parameter from `lv_canvas_draw_text` - Remove the copy parameter from create functions - Optimize and simplifie styles [#1832](https://github.com/lvgl/lvgl/issues/1832) - Use a more generic inheritenace [#1919](https://github.com/lvgl/lvgl/issues/1919) - Allow adding multiple events to an obejct
