Also, why do those buttons have to be on the right side of the field anyways? If they were on the left, one could always use them without scrolling even if the fields extend beyond the visible area for some reason ..

I've made a small improvement to this now in bcd227c - the field still doesn't shrink when you narrow the window again, but at least now when you switch to a different PR in the application that resets the width to fit the current window size rather than being forever more stuck at the maximum width you ever reached. Similarly, when creating a new PR instance the table grows when you widen the "new PR" window, doesn't shrink again when you narrow it, but at least resets when you close and re-open the window again.

I'm not really sure what the correct behaviour here should be - we can make the fields always track the parent width but everything I've tried for that means that they initially start far too narrow in the "new PR" window, and also you don't get the scroll bar for very long values (e.g. a really long creole:// URI - the only way to view the part that has run off the right is to click in the field and then move the cursor to the right with the keyboard).

I can think of two sensible-ish alternatives to the current UI

1. move the buttons into their own column in the table, to the left of the current text field column, then there's a trick you can use on an N-column JTable to make the left M columns fixed and the horizontal scroll bar only scroll the right N-M ones
2. disable horizontal scrolling altogether but do the kind of thing that Excel does when you are editing particularly long formulas and have a "..." button to pop up a multi-line editor if the single line one is too cramped
