Widt of columns in translation screen needs some tlc

This issue was in 3.5 but is still in 4.0. The column width of the translation screen needs some tweaking.
The most rigth column really does not need to be this wide. This space could better be given to the two column to the left of it.
I got it working for me now, but not everybody has a 34 inch wide monitor.

(or allow column resizing, That would work too of course)

I made a screenshot to show what I mean.

Warm regards,
