TODO

• Windows: 'app' failed with exit status 2

Closing temporarily to avoid unnecessary load on the CI. Will reopen when I'm actively working on the PR again.

@valgur I made some changes to this so it works locally on my Mac. Should I post them here? If so, what's the best way to do it?

[valgur]

@DoomHammer You can open a PR in my repo against this branch. Or add them as comments with suggested changes, if the change set is not too big.
