Customize Project UI for my needs

Hey there,

i would like to ask, if it is possible to customize the user-interface of my created project in zoho?
Currently i have many aspects that i do not need and that only will lead to confusion by my customers. I want it as simple as possible, just with the aspects i need to work and communicate with my customers.
So for example, is it possible to deactive the calender, timesheet and milestones?
Would be great if that would work! Because if it would work this way, and we can customize the project-ui for our needs, we would definitely use your service in the future and of course pay for it.

Hope hearing from you!

Thanks!
