yep, this "feature", this plague upon my peaceful life is garbage. There should be a way to set the default behavior.
So let's say the Evernote programmers got tons of feedback that people want this feature, make it the default, that's ok, but leave a way to keep a friggin regular, non-strikethrough check box type.
It's hideous how much fighting I have to do with the program to get it to stop auto formatting or work around this feature.
One of the other bad programming ideas is that if you click the check list icon - you can only undo, you can't simply click the check list (or check list next to bullets) to toggle it away.
I do like EverNote overall but I'd score this feature as a -8 out of 10 (because like I said, it's a plague on my peace and productivity and that's not why I pay for software).
Now that I've vented, and google searched and found this forum that says this bug is a feature I did some exploring and it seems if you click the plus and then the check box you can insert them individually so it's not impossible to do (again, I want the whole default to be customizable).
