Hi,
thanks for writing.
The first suggestion is actually amazing and a pretty obvious lack of usability.

For the second suggestion there is https://github.com/JonasJurczok/factorio-todo-list/issues/34
I'm not sure how to implement that right now, though.
But it is on the roadmap :)
Thanks for the suggestions!
Not sure if you need to do it yourself. Not exactly. The new rich text system lets you do this: [gps=x,y] which creates links to map positions. You can currently trigger this with "ctrl + alt + click", which logs it to chat. Maybe you could find out how this happens and then do the same except you'd simply pre-populate the task with that rich text? And the marker could just be a normal map marker that the game already offers. YARM generates these when you add a resource patch, if you want a reference for how to do that.
Fwiw, I actually personally want the subtask visibility thing more, because I'd really like to be able to see my next "step" in single player (which I play exclusively) without having to open up the whole task list. I am assuming that the plan was to have the current subtask appear below the current task in the "mega-condensed" view, or whatever you want to call it. The button. If it wasn't the plan, then consider that a feature request. Love the mod though. It's been a must-have for me since I first downloaded it.
