The world maps and other overworld maps in many games are often multicoloured. What this means is if you decide to use say red as your font colour to write on the map, half the time the letters will blend into the background. You can run into the same problem even with a mostly black and white map, if you use lots of different colours to differentiate information. What I would love to see is the ability to write in automatically outlined text. Basically just adding a second colour box to the text tool allowing you to keep the outline "transparent" (so, off) or pick a colour that allows you to make text with contrasting outlines, making it all that much easier to read.
