Thanks for the reply!

As far as I can see though, there isn’t a way to lock the side-scrolling for the two split windows? This sadly makes it impossible to use for me, since I use files with many columns, that always need side-scrolling, and in that case I would need the column headers to move in sync when I scroll the bottom window with the contents, otherwise I still can’t know which column is which.

Is this also possible?

Could you otherwise add an option for it?

It would be a very useful addition to this already nice split feature!
