Interesting can you edit code in the text view too? Wonder if this could be the one place to write your code too.
We decided to focus on source exploration instead. Sourcetrail is made for the second screen. We implemented plugins for the most used source editors to enable easy switching. Please have a look at our documentation: https://www.sourcetrail.com/documentation/#CODEEDITORPLUGINS
Nice work; seems like you hit a nice medium between trying out something new and keeping it connected to the real world and practical. :)
