It would be nice if we had decorative planters of different tiers instead of just crude planter.
I agree. Though we can just use the actual planters (which has different tiers). It’s nowhere near as practical, but it is a possibility. Plus there are a few plants that don’t have a decorative version, such as the crimson lotus, so using the functional planter is the only option there.
And it would be awesome if they add special DLC themed planters.
In my experience, sadly no. Not that much vertical adjustment. Though much can be done with some creativity and the right location. I can put up some screens later perhaps, if you’re interested.
