The activity name is displayed on the top right corner of my screen:
- at startup (the name of my default activity),
- when I create a new activity.

But as soon as I change activity, this name disappears. Only the cashew (is it its right name?) icon remains on the top right corner, with the menu when I click on it, but without the name of the activity. And the name don't come back, even when I return to a previous - and previously named - activity.

To determine in which activity I am, I must display the whole activity bar, instead of just looking the top right corner, what is less comfortable and less quick.

If someone would know a solution, I'll be very grateful.
