Maybe setup that you can use the CTRL key or something to place floor tile down to cover the entire floor or based on how much CL Coins you have available same with Wall paper.
Having to click on each little square when having a big floor takes a good bit of time, and most of the time, having to click several times on 1 square to place 1 title.
Where as you could click on 1 square, hold in the CTRL key, and fill all floor or wall with the chosen title/wall paper. A lot easier, and less frustrating.
Can't edit... Title should say "Floor Tile" not title... /sigh
