- For the outside items (town improvements), hold your finger on them and wait a while. It seems to take more than 3 seconds. (Tip! Pressing harder on the screen doesn't help!) Eventually it will pop out of place and then you can reposition it or rotate it. To get rid of it altogether you'll need to demolish it. Dynamite is available in the store, but I forget what category it's in.
- When you drop a mineral or a mature flower plant in the mayor's house, it acts sort of like a piece of furniture acts. The mayor won't pick it up. Just hold your finger on it until it's moveable, then drag it over to the tool tray. It will pop into your inventory.
- The developers say more stuff will be added, but I am not the person who knows what or when. When I feel that each day is same-old-same-old, I do one of three things: start a new project, either to answer a question* or add a complicated park feature; or take a break from the game for a few days; or remind myself that people get all excited about other games that last six whole hours! Woo! I've been playing for months now and by taking occasional breaks from the game it is still fun.
*My most recent question was how to get rid of a townie with a bad attitude, but I'm still too chicken to post the answer I came up with.
