- It really could use an update It is such a shame to see as useful tool as this one being abandoned

- I like it , but can you please: 1. add an ON/OFF BUTTON. The only way to turn this thing off is to remove the extension. 2. Update it to bootstrap 4 . The Extension doesn't show (xl) size.

- its good but you NEED AN ON/OFF BUTTON. The only way to turn this thing off is to remove the extension. Which I am doing now because I simply need to take a screenshot. Super annoying.

- I like this app. But I think it would be better, if it will have opportunity to set custom screen sizes. For thous people who wont to change bootstap default break-point and to test it.
