Auto-indentation in Ruby
Please add or fix auto-indentation in the Ruby environment. I believe other languages have this. It's a pain for our interviewees and we're exploring other platforms because of it.

It'd be nice to have this option in case both parties agree to record so we can replay during debrief
Questions to check the solution performance.
A good developer can performs a fast solution. If exists some questions that check the execution time and compare it with a expected time, this will be so good to know if the developer knows the fastest algorithms. Another suggestion is to verify the algorithm complexity. Thus, if the question expected a solution O(1) but the developer solved using a O(n) for example, then it will be useful to check the develoler knowledge.
