Is there a way to streamline apps together?

Is there a way to streamline apps together?

I use the Zoho Invoice, support and CRM apps. Right now I have to have three tabs open. Is there a way to have one tab open and toggle between the three Zoho apps?

For example, on Zoho Invoices there is a drop down where you can change to some other Zoho apps.  

Zoho is pretty awesome, one thing I find it the UI is not consistent.

Thanks for your help and great products.
