Improvement : Reduce number of action for "Mark all items as read"

[Benooye]

Thanks a lot for your wonderfull app.
I would like to propose an improvement for handling the Mark all items as read.
Indeed today this requires:

1/ to click on the "mark all buttons" on top right
2/ to select all items
3/ to press "previous" to go to the list of articles or group

See screenshot below (sorry in French)

In fact you could simplify the process by appliying the 3 steps with only one click on the "mark all buttons" (see number 1 on the picture) on the top right. It would allow a more efficient use of the application.
The selection menu for the duration could be opened only for a long press for example

Thanks in advance and best regard
