Awesome, it's really cool that you took the time for looking into my extension!
I'm unsure what you mean about the missing mod support, could you give me a hint of what did not work for you? A known issue is that the code completion currently does not pick up items from depended levels (as it only scans the *.lsf files in the current project directory). I've tested the extension against projects depending on the main game and the goals of the main game showed up. However my code currently strongly relies on an up to date story.div being present as it reads the goals from it. As this strategy comes with a lot of issues attached to it, the next version will pull this data directly from the other mod directories or the pak files.
Indeed, I don't have early access so I was not aware of the new files for ignoring unused databases. Thanks for the good explanation, I will implement that once the DE version has landed.
