@chipsnblip Thanks.
I suspect @thief122 would hopefully be able to provide more feedback as to whether this is something he'd use and how, given that the use case was brought up by him :)
In terms of the overall approach, I think that it's always positive to set up a GitHub project for anything you'd do that's on the creative/technical side. It's good for learning and sharing above all. It'll also help you get feedback - and even help - from other people who are interested in the same problem, as well as thinking about how to bring it to the wider audience. So yeah, I would recommend that, should you be interested in investing time in this. Not sure at what stage you are, and where do you see this heading - as well as whether this solution is something that people would in general use. Definitely getting feedback from the end users would help!
I suppose the key thing in all of these projects is that a) this is a problem that you are keen in exploring and solving, and b) that you're having fun along the process :)
My comment on the layout was just an option, as I was thinking about the problem. Indeed, right now it's just rendered on top of the game, which may (or may not) be ideal for those who will use it. That's kind of why I thought of using the wide screen real estate, but you may be right, it might not work on a smaller screen, or if the game is stretched! Well spotted.
I think there was a similar thread to this a while ago, though I can't find it. Might be interesting to see if this is indeed something more people would like to have and how, and maybe take it from there if you're keen to!
Best of luck.
