--EDIT--
Just seen that it has already been reported,
HERE sorry
----------
I often use my mobile phone to check the forum when I am not in front of my PC.
Not sure if it has been reported before, but I see that the header content width is not adjusted to the table below (forums).
This is how the B4X page is seen in my device when I open the browser (top-right notification icon seems cut)
If I zoom out to see the whole width, this is how it appears (top-right content seems to exceed the colored header width)
It's not critical at all, as it still allows to navigate normally.
