This pull adds a new global variable called creative.formspec_add
that will allow mods to add to the creative inventory screen
without the need to fork the mod altogether. Simple solution
that works already for inventory_plus' BACK button
Currently any doors viewed from underwater will disappear but removing the line 'use_texture_alpha = true,' seems to fix this. Thanks to Thomas-S for finding this glitch.
Books still don't wrap long lines of text properly so until this has been sorted out I suggest reverting back to a previous working formspec which lets players read books properly until a fix is found (and maybe scrollbars added to texarea's). Also adding a recipe to blank written books.
By adding the timer to the tnt:tnt_burning node it will help mods add the block and cause an explosion after 4 seconds instead of doing nothing like in it's current state.
