12625	Propose to merge multipolygon tags into polygon tags when taking an outer polygon off the relation	Penegal	team	"Hello, there.

Currently, when I remove an `outer` polygon member from a multipolygon relation, the removed polygon often ends up without any tags, as its tags were totally inherited from the relation. It's a problem when I fragment useless multipolygons in smaller, unnested polygons, as I can not even copy all the multipolygon tags in the polygon tags, as the relation edition window lacks the ''copy all tags'' contextual menu item, and all I can do, AFAIK, is to manually re-type them.

This situation often shows in my rural area, in which the first created `landuse` polygons were from Corine Land Cover, and the contributors often added finer `landuse` polygons by converting the CLC polygons in multipolygon relations; this leads to big, unnecessary multipolygons which I'm fragmenting to remove the relation. In the end, having to re-type these tags slows down the data improvement, and I must add that it isn't motivating to improve the data with this workflow.

This problem can be, IMNSHO, easily addressed this way: when an `outer` member of a multipolygon relation is removed from the said relation, jOSM should propose to merge the relation tags in the removed polygon, possibly by displaying the tags merging window currently displayed when merging ways with different tagging. That could drastically speed up the splitting and suppression of multipolygon monsters.

Hoping I'm not asking something stupid ;-)
