Need to edit and change order of presets, also edit shortcuts. Otherwise it's a good tool.

Well, nice efforts but, until you add positions (top, right, bottom, left), its useless! Just a quick note, most people needs window resizer addon because they are using large (4K) monitors and they open 2 or more windows at the same time. So, positioning a window with the Short Cut is most important for them. Just sizing a window will not do much!
