-### Feature
-
-- [ ] Move dependended plugin from GacUI to Vlpp (optional)
-- [ ] Cannot change column size during datagrid's bounds changing, which is by designed and this could be solved by calling InvokeInMainThread. But new feature for solving this is under considering
-  - [ ] Considering GuiBindableDataGrid updating columns' sizes according to configuration automatically, and call `GuiControl::InvokeOrDelayIfRendering` (indirectly) inside `DataColumn::NotifyAllColumnsUpdate` when necessary.
-  - [ ] Like a table, a column can use `Absolute`, `Draggable` and `Percentage` to specify a column size. Only when a column is draggable, users can use their mouse to change the size of a column, and then trigger `IColumnItemView::SetColumnSize`
-- [ ] Consider drag and drop support, with column drag and drop
-- [ ] New item arranger that can accept a `GuiRepeatCompositionBase`
-- [ ] **Update Release**
-- [ ] New default control templates with animation, written in XML generated C++ code.
-- [ ] A window can be called to update all its controls' and components' template
-- [ ] Tutorials use the new default control templates
-- [ ] **Update Release**
-- [ ] Fix GacGen reports only "error dumping resource file" while the resource file contains some syntax errors preventing GacGen from reading it
