Thank you for your inquiry – this is definitely on our to-do list. Currently the plugin is set for US dollars, BUT we are working on supporting other currencies. This will be in the next version, but no date set yet for that.
Also, thanks for the concern about higher res tutorials – I have had the same concern in generating them (YouTube compression does blur them a bit). I will endeavor to improve the quality. Is there a particular video you wish to see improved/expanded upon, etc. and I will start with that – for that matter, do you have any suggested/desired topics to cover? This is a brand new plugin/endeavor and I am efforting to generate content on a daily basis.
