So, i'm furnishing up my house and I thought of the idea that, perhaps in the future players could be able to buy stables to put their mounts in player owned houses? Similar to the statues that let you show off hats, each 'stable' could cost 1 maybe 2k and holds one mount each. The mounts will obviously do nothing, just stand there and look pretty. A way you can get mounts into the stable is by simply riding them on top of the stable, then to clear it you click on the furniture options and have the option to remove the mount from the stable.
This would fill up a lot of space in player owned houses, and essentially make it look nicer.
Alas, this is just an idea of mine. Thought it would be a nice feature, though you may disagree.
