The 5 most important things that you need NOW !

I just started really building in Sims 4 and as former big Sims 3 builder—this is what I feel—I need NOW!

1. Better matching colour swatches: so many look like they might match most/other EPs but they don't, some just are missing and others don't match much. In some cases top cabinet swatches don't even match bottoms (L&D for example).
2. Spiral Stairs: I love these (as they are extremely condense) for two floor solariums, greenhouses, and Victorian builds.
3. Mirrored versions of  existing doors: some doors have unique looks on either side but the opposite is often needed.
4. Steampunk build/buy set: my favourite theme and though I can work with many items to make a passable Victorian/Industrial theme—it isn't Steampunk enough for me.
5. Debug improvements:  you cannot change light colours/dim and add plants (harvestables) in various stages without being in live mode, needed organization (of plants/harvestables, visual spawners, etc.), add missing debug items (hidden to players but used by devs), etc. As well as a way to not have to repeatedly re-enter debug cheats while building.
