Issues clean-up

[nurSaadat]

Problem

Some issues are technically closed, but are still open.

Solution

I suggest conducting a revision of open issues to see which ones were already successfully closed, to keep the repository clean and make looking for open issues more effective.

This issue can be mentioned, when requesting issue closure.

I understand, that not all issues with merged pull requests can be closed, as the issue may still be not solved. It then requires a bit of research to understand whether the issue is still needed.
