Ok, so first off, the huge crash I was getting was because of using a global variable for holding the link and not a local variable, and when 2 threads attempted to use it at the same time, my app would freeze and crash, so now it runs great!
‎
Some of the QofL improvements are adding keyboard shortcuts and the ability to close tabs by pressing the middle button down, like a real browser!
‎
Then there were a lot more comments that I am so close to being done!
‎
Overall a decent 2 days; I’m definitely getting a bit bored of the comments, so my plan is to work on my other project for a bit and come back later! But yeah, a good day. :)
