Thank you for sharing your impressions with us, we really appreciate it as it helps us get better!
The Shoptagr button is movable, so if it covers something on the webpage, you can drag and drop it.
As for the notification preferences about price changes, you can manage it in your account settings by turning "send me price reduction alerts" on. Thus, Shoptagr will automatically notify you once the price changes :)
We will take your suggestions into consideration for the future to make the app even more convenient :)
