SolarBox review for Shopify Inbox

As a free App it is definitely a handy chat feature. I would like more customisable features. E.G When you're using a mobile device and browsing on the website the "Chat with us" Box is way too big and crowds the screen. Also you need the option to close the box as it gets annoying / in the way, in particular on the mobile. I have spoken to Shopify and they said they're working on these upgrades. If Shopify can apply some edits and changes then my rating would improve.
