[Freeciv-Dev] (PR#6340) gtk2.0 / 1.14.1beta: item being produced should be first on queue

["Guest" <rt-guest@xxxxxxxxxxxxxx>]

Before, if my city came under imminent attack, I could easily move city
walls or a defensive unit up the list to be built now.  Now, to change
priorities like that I have to go to the list of things to build, drag
city walls to the current production, double-click on what I was
producing, and drag it up to the top of the worklist.  This is the
single most annoying part of the new client -- and it's a regression
from the older gtk client.
