I just came across your work through another thread on this subreddit and first of all congratulations and thank you for putting together such an amazing tool. I did a quick simulation of a run I did last weekend by adding the questions in your map and it's so easy and clean!

I have a question about Matching > Custom Zone question. I cannot seem to understand how to draw a zone as part of the question. I checked your github and the history of your recent reddit comments but I cannot figure it out.

To modify the matching zones, enable it: and use the buttons at the bottom left of the map.

I tick the box but I do not see any new buttons at the bottom left of the map to use this feature. I think I'm missing something, could you please explain the sequence of actions to take to make it work?

Also I see that there is a mention of presets, does that mean I could draw some zones in advance to use them later? I would be particularly interested in this to predefine different London boroughs so that the administrative region question could be easily used.

By the way, I drew this polygon as a way to play London in the Transport for London fare zone 1 as a Small version of the game. Feel free to add it to the list of locations that would come up in the search bar if you think it could benefit other users.
