When you select a tag to display all tasks.
When I select a tag to TODAY , I see all tasks with this tag but only for TODAY
Same thing if you select a tag to NEXT- I see these tasks h tag but only for NEXT


Why do it?
Due to the fact that the problem can install multiple tags. Tags replace contexts to fulfill the terms of tasks and contacts (unites tasks associated with one person)

If I have a meeting with a man before I met him, I chose tag (associated with this person) can look for other problems associated with it. It is possible these problems can be solved at a meeting, even though the problems are recorded on different days

Of course you can use for this filter. But then you have to go into the list of filters (extra clicks and effort) and the filter will be too much - for each tag

In addition to viewing the task of the filter, mixed and completed tasks are not complated
