Look at that, without even looking at this issue, I've solved most of these issues in #97 . Other things still on the list:

• [ ] more flexible layout #91
• [ ] add trace option #87
• [ ] fix hacky json / inputs.py setup
• [ ] Add option to Plot two datasets to compare (a la 'constph-grant' or 'GK v. WT' requests)
• [ ] Make it a bit clear what the default nsamples is
