openHAB dashboard - dashboard.cfg options

Hi, @Pali, @kubawolanin

In this post: Addon to add external links to openHAB dashboard

Pauli asks:
Any other options?

Yes, please: Can the size of the tiles be adjustable. I have ran out of screen space. Some of us are running numerous services related to openHAB and the size of the tiles limits the options to 12.
