I have been using the Juno-LT interface for working with Julia, and it's been great!
It would be nice to be able to split up code into sections (like the cell feature in Matlab and IPython notebook) and evaluate each section separately. I'm not sure how sections should be defined (Matlab uses %% to begin a section).
The current functionality of being able to run selected code (http://stackoverflow.com/questions/29411110/execute-a-block-of-code-but-show-all-results-in-julia-juno) is already pretty good. For the sectioned code, it would be preferable to only display the result of the last line inline.
