Number of activity buttons in the notification bar

[rendel470]

One more question.
In the curtain, only three activity buttons.
Is it possible to fit in the curtain with a notification, for example, five activity buttons (instead of three)?
Or it will greatly reduce the area of pressing buttons?

And these buttons of activities, must (after they are pressed) open the main window of the program? (is it possible to make it optional, that is, these buttons in the curtain, to open/not to open the main window?)

Clicking on the current activity (in curtain) the same opens the main window!!
After all, the notification curtain is created to not always open the program window.
Otherwise, why do we need activity buttons in the notification curtain, if even without them you can open the main program window from the notification curtain (and press the activity there)?

Whether increasing the number of buttons will improve the usability is not so clear for me, but for the second part I perfectly agree. The buttons shall not open the main activity after selecting the next activity.
