Sorry if these ideas have been mentioned before, I searched first and couldn't find it, but if it has been let me know and I will pledge my support there :)

Just a couple of ideas here to make organising my showcase easier/better.

Remove all option when wanting to remove things from a room, this would make it easier then removing them all one by one if I want to put them in another room.

Show how much more you can expand a room, I did not realise I could not expand it more then 70 so show it as 60/70 etc.

Be able to change the order of the rooms, I have all mine labeled into categories and then realised I can't expand the first one any more so added a new room to put the similar stuff in (my animal decors) and now they are at opposite ends of the showcase but I would like them next to each other and the only possible way to do that is remove everything from the rooms and move them to the next one along. So instead it would be great if there was an order list (maybe like decors on a lions page) where we can enter 1,2,3 etc in what order we would like.

Thanks :)
