Recurpay: Subscriptions app

I did not see an option to add entire collections to the subscription plan. I found it to be way too time-consuming to add each individual product to the subscription plan, especially since you have to create multiple plan types in order to achieve a tiered subscription. For example, you have to set up one plan for a monthly subscription, a separate plan for a 2-month subscription, and then a third plan for a 3-month subscription. Each plan requires you to add each product manually -- again, there was no option to add entire collections to the plan -- which took WAY too much time. Not worth the effort when other apps allow you to create a tiered subscription right out of the box, and allow you to add entire collections in one click.

I un-instaal this application. but once I have done guess what, its now showing in my site! its now showing in all pages!!! don't install don't know how to fix this gar..ge.
