暂不支持子列表

Hello, I would like to pass on some considerations to @Hufe921 when implementing this feat. I once tried to implement this improvement and I didn't finish the work (I still have the changes). However, one thing I noticed is that before implementing nested lists with different types, it is necessary to make a change in how the editor positions the cursor at the beginning of the line when it has one or more tabs.

In other editors, such as Goolge docs, when you have a list regardless of whether it is normal or nested, the initial position of the cursor always respects the tabs added at the beginning of the line.

In the case of canvas editor, the cursor will always go to the first position of the line, regardless of whether it has tabs or not.

I didn't have more time to work on this, I had some problems when making the first change, the cursor position according to the key pressed (up, down, right, left, Enter...). If there is some time left, I will work again to send a PR, or I can also send the style as it is for someone else to work on.
