Please add the following features to the Image Editor: Ruler Tool. Click from point A to Point B, get the distance in pixels. Points A and B become anchor points, so you can move them around to adjust the measurement if your initial click wasn't precise. Once laid down, the ruler becomes persistent metadata that stays with the object, like a selection or brush. That way you don't have to keep re-measuring, but can measure once, leave as a guide, come back to it if you need to reposition or resize the ruler, or delete the ruler, and you can have as many rulers as you like laying in their own layer in your image. Rulers. At the top and left side of the image, rulers that can be toggled show/hide. Showing tick marks in pixel units, so you can accurately tell the size and position of coordinates in your image, with options for Base-2 and Base-10 tickmarks. When moving any tool inside the image pane, its X and Y position are indicated in the ruler. Guides. Click in a ruler, drag into the image, to create a guide line. The line is similar to a grid line, in that it's not a part of the actual image (it doesn't display in the game when the sprite is drawn). but it is a persistent part of the image editor data, and allows you to snap other drawing tools to the guide. (See Adobe Illustrator for inspiration.) Make Snap To Grid a per-tool option, rather than global. I end up having to switch StG off/on very frequently when switching between tools, depending on if I need the grid or not. If you won't make this a per-tool option, Ctrl+G to toggle snapping is OK. Make an option to allow different grid sizes for each layer in the image editor. When setting the grid size, include an "apply to all layers" checkbox. If checked, the grid size updated in all layers to what you just set it too; if unchecked, only the grid size in the current layer is set.
