Hey @Multirious I just wanted to ask about why you approached this using macros and automation
I had a similar issue, I wanted to use helix as the external editor for Godot, so I found your repo but decided to give it a try with a different approach

my take
plus the following config on Godot

I just spawn a alacritty.exe + hx.exe command with the arguments Godot provides when calling an external editor and it seems to work a-okay without having to wait for the automation/macro to run (though the repo is not really meant to be used by others as I haven't made it general, just wanted to quickly fix it for my issue)

But I got curious so I wanted to ask, if you don't mind, why'd you automate it instead?
