In the new 1.5 I notice that the admin/includes/boxes directory has been totally removed

many of the addons that i have installed had files in there for functioning...

gv_admin.dhtml.php -- gv edit
notes_buttons.php -- admin notes
reports_dhtml.php -- sales report 3.03

then in the extra _boxes>

image_handler_tools_dhtml.php -- IH3
notes_extras_dhtml.php
providers_tools_dhtml.php -- private area addon
sales_report_reports_dhtml.php
wishlist_extras_dhtml.php --wishlist 1.62 (I think)

Is that why many addons are not functioning right? Would we be able to add these files to the main admin/includes folder to get the functions back?
