Quick Resolutions by support team really helps, and this functionality took lot of time to find an app for, HiVar Provided the exact solution we were looking for.

Great solution to the hiding variants problem. Owning a website gives us little time to deal with things that could cost us conversion. Having a customer go through every product variant to see which one is available could definitely cost us the customer. I spent hours last night trying to import codes contacting shopify support trying to find a way to hide my variants because I have multi variant choices, size and color. Some of the odd sizes only have a couple color choices and the user would have to go through 10 to find those two, by the time they got to the bottom they would forget which ones were available. This app was the easiest solution I found and their customer service is very timely. They are like sending a text message to your friend, they also will go into your store and solve whatever you need. Most solutions just require one button but if you have a more complicated store the customer support will solve it for you. I definitely recommend the app, especially for dropshipping e-commerce

plugin conflicts with default add to cart buttons and makes it impossible for customers to purchase other products

Works very well to keep our customers from having to muddle through out of stock errors. We use many variants to segment our products, and HiVar works to easily hide those segments that are not quite available yet. The support from the developers has been above and beyond our expectations, particularly with regard to fixing small errors that we introduced as we continued to upgrade our theme.
