Hello. When I try to download a piece of chat, I most often set the time and do not pay attention to whether the checkbox is activated. Is it possible to make the counter inactive until the checkbox is activated? Or it better to automatically activate the checkbox if any value is entered into it.

This will be fixed once the PR (#390) is merged.
