User-defined tabs (similar to the "Comment" tab)

Description

It would be nice if we could use javascript to write information to "user-defined tabs", similar to the way we write to the "comment" tab. For example something like this:

request.userDefinedTab["myTab"] = "hello world";

If this is too complex, then we could have pre-defined user-defined tabs with predefined names. For example "tab1", "tab2" up to "tab9". And then we would do something like:

request.tab1 = "hello world";

Why this feature/change is important?

This feature can be useful if we have a lot of javascript code that extracts information from requests or responses, analyzes it, formats it etc. Currently we write everything to the "comment" tab, but it becomes cumbersome and hard to read. Using custom tabs could be very helpful for separation - write different information to different tabs.

Thanks for considering it!
