More Requests: Markers, Items, Tiles, Tooltips!

First: There should be some hotkey commands that allow you to click and drag things like markers, items, and image scaler tiles without having to switch the the specific tool.

Second: Markers need to have three different places they can be place: At grid intersections (as they already are), in the middle of a grid square, and on a grid line between intersections.

Third: Tooltips should pop up for ALL things, creatures, markers, items, etc, regardless of what tool or action you're currently using. Also being able to doubleclick (or maybe hotkey+click/double click) to edit markers and items would be great.

Fourth: You should be able to set the size of a tile BEFORE you place it.
