Thank you very much for your courtesy. I like screenshot is due to its
intuitive and simplicity compared to wording in many scenarios. Below
is some additional requirements I want to have with a decent
screenshot method:

1. Have the delay feature, so that I can do some operations before the
screenshot is captured, say, click on mouse button, open a dropdown
menu, and so on.
2. Have the post-processing feature, which can be used for some touch
ups on the generated screenshot subsequently.

I am not sure whether the recommended method here has these characteristics.

Best,
