Zoho Theme

Hello,

I was working in my Zoho, and I was suprised that I could choose a theme. Maybe its an update, but I like it.
When I switched to my contacts my theme was just gone. So my idea is, would it not be nice if the choosen theme is everywhere the same? It would make Zoho complete. Can you please fix it in any next update?
I would be glad to hear from you.
