Josh, check the IDE again man.
- Line number is displayed in bottom left
- Ctrl-/ gives you comment. Highlight multiple lines first for mass commenting (See Edit menu)
- Ctrl-[ gives you indent. Ctrl-] gives you outdent. Again, select multiple lines for mass-

I actually enjoy the simplicity of the IDE. I write OO multi-file projects (10+ files) in it all the time and enjoy it. I certainly don't feel the need to use Eclipse or Visual Studio to do what, for me, is "simple" coding.
Have another look at the menus. If you're not up to date on the IDE, you might need a download too.
