Move document to next split / window

Hi,

I use multiple splits a lot. One feature I mis is ability to switch documents between splits, so that if I have doc 1 in first split and doc 2 in another, I'd like to switch them

The easiest way to implement this is "Move doc to next split", which would simply:

• move doc from the current split to the next split,
• move doc from the next split to the current split,
• make next split current split (so this doc cam be propagated few more times)

also, "Move to previous split" could vork in reverse to this.

Regards,
Petar
