Sorry, Augment does not have access to the org this pull request's branch is from.

@sorrycc I want to provide more PR, but this PR is still in progress. :)

May I ask if there is any issue?

[sorrycc]

thanks for the pr! i like this feature, and it's also on my todo list.

i have tested this pr some days ago, and find the screen is twinkling heavily, may be i have too many providers enabled. i think we have to improve this ux first.

or, you can hold this pr to work on other pr first.
