I was just trying to filter the emails I was getting from the particular site and the time when I clicked on filter messages like these and then to Create a filter to this search, it opened some options which confused me being simple .
Now every option has checkbox which means a user can select multiple options.
So what is this?
- Is it something google did intentionally?
- Is there anything hidden about these checkboxes?
- Although I can't select never when always is ticked but to check never, I have to uncheck always first and then choose. So why not a different div with radio buttons in these two?
