Split the interfaces into several tabs

[Magicnetworks]

It would be nice to split the interfaces into serveral tabs. It is helpful when you have a lot of fields in an interface.

I have fudged this by duplicating interface views for each tab/record view I want and then using buttons that navigate to a URL in the record. 
I then use a formula to calculate the URL using the page ID shown in the URL. 

This works ok-ish but only in the legacy editor (buttons work differently in the new editor).

It is also VERY tedious and difficult.

I would LOVE to have proper tabs to separate the different aspects.
