Lately while playing KingdomIsland, I've been coming up with more ideas. Here are some of the following ideas:
Scrolling/Search Bar - If you follow a lot of people, or someone follows you, I think it'd be easier to search for that person or use a scroll bar instead of clicking the down arrow every single time.
Rooms - I feel like some rooms need a little more detail and scenery, but that just may be me. Not only hat, but different music for each room maybe. To give things more life, maybe have some things animated (f.e: Waterfall, ocean, fountains,lava, castle flags,etc)
Sitting - Usually you have to click yourself to sit and your character follows you where you move your cursor. Well, maybe we can just have a sitting button and when we click it, we can decide which direction we want to face.
NPC's - Like the mobile version, I believe there should be NPC's (non playing characters) that help the players out with frequently asked questions depending on what room they're in. But they have to click them and select the question that matches theirs.
Those are just some of my ideas. Let me know what you think!
