Currently, the designer automatically increase the width of parent containers when a control is moved or resize and goes outside the current parent size. But this can be problematic with bad paging in some cases. As the automatic grow may be needed, I propose to increase the parent size with a settable minimal step: When having set everything to have a width of 160 mm, just moving some controls can currently increase slightly the size (like 160.23 mm). But if the report has a minimal grow step of say 5 mm, in this case it will be resized to 165 mm, a visible size difference (therefore, layout can be corrected when the grow was unwanted).
