So I'm not sure if this will be possible at all, but someone might have an idea for a workaround for this problem.
So if I have made a toolbar, e.g. (short version)
class add_item(Panel): bl_space_type = 'VIEW_3D' bl_region_type = 'TOOLS'
But I would like to have this toolbar placed in multiple toolbars so it'd become something like this (code below doesn't actually work, just an example of what I'd like):
class add_item(Panel): bl_space_type = ['VIEW_3D', 'IMAGE_EDITOR', 'NODE_EDITOR'] bl_region_type = 'TOOLS'
Would something similar to this be possible to do without duplicating all the code for the toolbar multiple times, just to then change the
