Here are some of my suggestions and ones I have received to the Fluffy Wish List:
A Market similar to Lalia’s Market, but with housing decorations and located in the Homesteads.
Bound to Account Decorations
Many of the housing items are Bound on Acquire, such as the Store Property Guards and quest rewards, which could easily be Bound to Account in stead.
Stable decoration for your homestead house. Preferably where you can actually place your mount in.
Ability to choose from a handful of different housing designs/layouts.
Wardrobes in House
Wardrobe in house to place cosmetic items only in (the physical items) - this could help with storage/inventory issues as well.
Ability to set who can use the mailbox in permissions.
Such as nightgowns, pyjamas, slippers, etc.
Let us choose colours of the furniture we have already placed, so that we can match it to the rest of the house.
In addition to improvements on housing itself, I would like to see more reasons to spend time in the homesteads. Specifically, the following could be ideas to consider:
Ex: Quick Post, Horse race, Plant trees, Visit your kin hall, etc.
Ex: Visit each plot in your neighbourhood, Get x number of visitors, Add x number of unique trophies to house, Use transportation kegs x times, etc.
Such as implementing the tag game from Bree fields to the homestead, or a hide-and-seek game, chicken play (A Game of Hobnanigans). Festival-inspired games would be fun all-year in the Homsteads.
Make it possible for visitors to write a note in a guestbook - alternatively just to sign their name
Could be combined with Guestbook
Wall of Accomplishments
A plaque on the wall that, when clicked, shows the number of deeds/quests/titles or similar accomplished by the owner. Should be customizable which part/char you would like to show.
More Best Housing Events and similar
After the reset/foreclosure of housing areas and after the update, we would like to see more ‘Best House in the Neighborhood’ events.
Make it easier to visit others' houses
Ability to summon/join instances from neighbourhoods, House milestones
Tie a new Hobby to Homesteads
Make a homestead-based hobby such as painting, collecting items or learning music pieces to teach to others.
Last, I can't submit this post without ringing the bell for my pet petition: Please bring back the Mistletoe!
