thanks for your interest. I, indeed, consider my position very fortunate -- I am learning so much!
I decided to stick to Sphinx. Developers (programmers) will do technical reviews, so they will be happier with more readable source. Also my supervisors are technically skilled and they will revise my work in source. But apart from them, I'm on my own for now, I don't have any "peers" (fellow TW colleagues you mean?). The source will also be a subject of automated version control and it will be much easier to revise changes in this format.
I suppose the process will be very similar to our software development process, so I was suggested, because it is desirable that I use established tools. For now, the process is chaotic and it will require gradual improvement which can take some time because I have to produce actual results as well.
I don't have the luxury of time to experiment with more solutions which is a shame, I would love to. Thanks, though, for your suggestion.
Editor -- I'm currently trying out PyCharm Community Edition but I will definitely look into the Atom.
