It would be awesome if we could move around the label associated with a region, since it can sometimes be placed in an annoying way by default, potentially covering up some other detail. Same goes for the Path label, which sometimes extends out of a path (i.e. if it's used for city roads with 90 degree turns).
Furthermore, this could be incorporated with more granular label manipulation. There's another suggestion for rotating and curving labels, why not allow the same for region and path labels! To be a little extra, it would be cool if there was an "advanced" label editing window. Have the same simple one there is now but add a button (or whatever feels good for UI) that shows more customisation, such as: more granular text size, the space in between the characters, the rotation of the label and the curvature of the label.
