RANGREZA USA review for EComposer Landing Page Builder

Could be a good application but did not meet my exceptions so uninstalled it - now reviewing my theme code and notice there are EComposer codes left in at least 21 .liquid files. I have been manually trying to remove all. I am hoping it would get remove automatically once uninstall so people dont have to deal with it. at least that what shopify require from developers once issue "Build For Shopify" badge
