One thing I have noticed is that the developers consistently when they give us new deco: give us deco that is big in size (same as an ordinary building: 2x2). deco like this is underutilized because it runs into space constraints with lvl 50 players islands.
what we desire, and would buy (at least for coins from other players who then spend gems) would be 1x1 sized deco. while we have some 1x1 deco in this game - more (especially flowerbeds) would be bought by players if made available. especially 1x1 deco designed to work together with other 1x1 deco.
while I would prefer actually useful items in this game over deco: if you give us some - make it small. items like the golem, christmas tree, and rabbid rabbit have no place on my island due to space constraints.
