Good but needs a bit upgrade

I tried many downloads manager plugin but this one was my favorite because it is so simple and does what it needs to do.
The negative part: The plugin needs a bit upgrade, it needs ReCaptcha and A5hleyRich you should really answer for the plugin related questions. Make a premium version and care about your downloaders I would even pay 30-40$ for a lifetime use if a captcha addon would be available. Take these into consideration, you already made the hard part the rest is not a big deal.
