it is I again !
the crafting tabs currently overflow past the tab frame when you have more than 8 tabbed menus.
for example at the moment I have the standard tabs, plus archery mod & metals mod which both add tabs, today when i went to install something else it added ANOTHER tab (forge mod) but it did not create any paging arrows or anything to page down (instead the icon appears to simply overlap the tab frame) maybe it happens with more than 8 but at the moment there's no apparent control for the tab maximum or a way to make it page properly.
some mods also have recipes with a LOT of ingredients and instead of filling the frame in grid columns of 3, the ingredients simply overflow off the screen in some cases.
