I guess this works, but it is WAY too many clicks in my opinion. I frequently scan sheets of stamps into paint.net and need to do some cropping and selection. When I do so I hit "S" select my section "CTRL-N" and often hit "ENTER". However this used the default 96DPI. So I have to "catch myself" and make sure I manually change it every time. CTRL-N is so much quicker than opening a blank image + it is already sized for what I need (and I am not prompted to make a decision about resize).
Perhaps if you are using the tool as a graphic designer always creating 128x128 graphics this makes sense but for those that are using the tool in a more non-traditional fashion it is little aspects like this that make it tough. Even a "remember this" checkbox/icon that puts it in storage/preferences and sets it everytime would be a huge time saver.
