Hi, I'm just starting Odoo Online (SaaS) and want to find out if I can customize/change the default layout and interface (eg. re-arranging the order or grouping the apps etc). I can't seem to find any answers or documents for this. The 'theme's from Odoo appstore doesn't seem to work as the third party app is not supported for SaaS Online. 

Any feedback would be much appreciated.
