jQuery Grid Plugin – jqGrid

Hello i'm new on this forum, and i've noticed a little problem : 

I user jqgrid in french language, and the search dialog is too short to display all search fields, so i've changed the width in jquery.jqGrid.src.js on line 6801 to 600px instead of 450px. I think this is not a final solution, because if the inside form is larger due to specific css styles application, i'll have to change the value again. Could this width be automatic for next releases of jqgrid ?

thxs !
