@javaJarrett I've never used intellij but I've used netbean on ubuntu and I think one called bluebird both were pretty decent and free. I suck at Java but had to take a class in school so that's about as much help as I might be though.
when you’re in dev tools in the browser, there’s a special cursor you can use to check styles of elements on the page. When I use that, and I go into an invisible box, a scrollbar allows me to navigate a range of text that is overwise invisible (like a slot machine; you only see some things until the new things ‘scroll’ into view). However, this doesn’t work with the default cursor.
