Zoho Forms for Activity Recording

Zoho Forms for Activity Recording

Not super thrilled with the UI and complexity of recording activities (tasks, calls, meetings) -has anyone here tried using Zoho Forms to replace the activity interfacing? I know it's possible to create related list items with forms so I'm curious if anyone had done this - perhaps implemented with custom buttons?

When doing this, would it then be possible to disable/remove the existing calls/tasks/meetings button in the activity related lists?
