A few keyboard shortcuts have been added today, also the ObjectSelector got a little, still mostly empty, toolbar. When drag&dropping objects they now scale correctly to the current zoom level. A context menu is now present as well.
A new feature is uv-coordinate based object flipping, which is nice and simple, as it doesn't change the object shape. It however is a little redundant, as the same could be done with rotation and scaling. One big issue right now is that its to easy to end up with holes in the map, either due to float impression or duo to scaled object that don't fall on clean integer coordinates, the hope is that flipping might help to limit that.
