3. There are a lot of helpful tutorials online regarding optimizing JS – this is the link you were provided and covers the basics: http://code.tutsplus.com/tutorials/10-ways-to-instantly-increase-your-jquery-performance--net-5551

Hey vilvas,I looks like CodeCanyon is lacking in the donation slider department: http://codecanyon.net/search?utf8=%E2%9C%93&term=donation+slider
I would recommend submitting it. However, seeing that it is a pretty simple item and there are probably freebie items similar to it on the web, I would try to find some unique settings/features/design angle to work into it before submitting it to insure it gets approved.
