No more Zabbix screens in Zabbix 6.0 and problem with dashboard

[taken]

Hey guys.
I use for long time Zabbix 5.0 and just update to 6.0. After update all my screen move to dashboard but i got problem with size....
In my old screen i got 14 big classic graph and now i got 10 big and 4 little because i think there is no space.
i am not sure.. but i am unable to increase size of this 4 graphs looks like size limit of dashboard.
There is any option to increase size of dashboard?

Best Regards

Ok i think i got it in defines.inc.php:
DASHBOARD_WIDGET_MAX_ROWS

There is option to change this forever? because after update i think he back to normal 64.
