Shrink offerbook chat when offer list and user profile are open at the same time

If there is the offerlist column visible, and you click on a user's icon to see their details, this happens:

I am on a fullhd screen.
Since the offerlist is already gauged to its ideal size, the only remaining option is to make the offerbook chat less wide, at least until any of the two other column is closed.

Yes, this is an issue.
Two things are needed to improve it:

1. The use of a a split pane or similar so that we can slide and make the chat window smaller (offers now are pretty small so there's room to shrink that window). Same concept can apply to the offerlist.
2. Change the interaction of how user details appears. Perhaps an additional column is not the best.

On one hand, 2 is a lateral approach I appreciate, on the other the column for details is a consistent factor across the application interface and it's not a bad idea to keep it as is. No strong feelings about either.

Lateal-lateral approach: make the user details column a hovering component, that will disappear out of the side of the screen after a certain kind of interaction.
But I guess that for consistency, it should always be presented this way wherever in the application, and maybe it's a coding nightmare in javafx. I know it would be somewhat trivial in css (+javascript).
