Hi!, I've following this for several months already, and I created this account just to know how this process going
I'm a Windows 7 user, I've already gone through windows 10 but I sticked to W7 again (for working purposes and because I like it a bit more)
Still there're way more people with W7 than with W10, and W7 also has extended support till 2020.
May be there's no need to start developing it from 0. I assume you have already a version of it, so I would like to know if you will check if worth it to make it work for W7 (which will be great! )
