It is just perfect addon for self-education!
Very Nice
most (if not all) of the snippets or materials are updated on February 2019. That makes it a little bit less relevant cuz a lot things might have changed
good job, I will recommend to my students
good job
The tool is great but it has not been updated for a long time. the Snippets keep repeating and nothing new it makes me a bit boring
Thank you for making this. This is awsome. However, I encountered a serious issue (at least for me). I wanted bookmarks bar to be shown ONLY in NEW tab. This extension is preventing that.
Great idea and it really helped me while learning. It would be better with a bit more languages.
I dont like the new tab stuff, I wish it had a site as well
I really love the idea, any plans to add .NET/C# in the options?
