@HessethRan, it's fine to add your list here. Many of your requests already exist on the index, but I want to address a few things in your post that are not on there.
First, when it comes to specific styles of objects that you have requested (such as round and oval accent tables) or specific appliances, etc., I think we can all agree that we'd like to see them as well, but to go to that level of detail in the index is going to cause a lot of clutter, and also, I've got a hard limit of text in the index that I need to keep under. I believe (I hope) that the gurus are checking the index for main points and then reading our posts for the details, so your entire list will get seen.
Regarding mirrors, they are not shiftable because they are an interactive object. In order for the sim to animate properly when doing a mirror interaction, the mirror needs to be at a specific height. What we have requested is to possibly get some mirrors that are for décor only, i.e. are not functional, so that we could shift those. I personally would LOVE it, as I am not done with my mirrored structures concept. ;)
I am adding your request to enable shelves to hold more objects. They do currently support some 1 tile objects but not others, and it would certainly be helpful if we could place more and larger items on them.
