Where to add / hook / integrate query building plugin

[kodymoodley]

I am planning to package the functionality of the tool in the image below as a plugin for Yasgui. It is based on the idea of the Wikidata query service but with additional functionality, and it can be used on any public-facing SPARQL endpoint, hence the motivation to add it to Yasgui. Obviously I only plan to integrate the functionality highlighted in the image below (the other features are already in Yasgui):

I need some advice on where to best integrate this into the front-end as a plugin. I guess my first choice would be whether to put it into Yasgui or Yasqe. It doesn't really make sense to add it to Yasr because its not to do with the results but rather for querying. My initial thoughts were to introduce it in the Settings menu as a new tab with the Request method forms. Like so:

Any advice / pointers would be very welcome.
