When I filter by Tag in the "Today" box, it works out pretty well. However, if I go into the task details on Windows, and then I click the "back" icon/button then the filter will be lost and all tasks will be shown again in Today. This isn't convenient because I want to focus only on tasks with specific tags, but this seems to be impossible with the current version.

Similarly, on Android the same thing happens after I quite the App and open it again, the filter by tag is lost and I see all the tasks again. There should really be a more visible way for us to see that a view is being filtered by a specific tag, and the filter should be preserved until we decide to, not until we click the back button.

Many thanks.
