Additionally, several comments implied that AgileBits was hiding the option to buy a standalone license, so I looked at their pricing page[1]. I have to say I agree; it is not listed as an option alongside the two subscription options. In fact, you have to scroll all the way down, to the end of the FAQ, to even find a mention of it.

I'll concede that a subscription option might be better for some users, especially those using it on multiple devices, but I think AgileBits should not be hiding the regular license option.
