Reducing RAM usage

This extension is taking up around 4-5GB of RAM, making it hard to use together with the game open. I suspect it's because my workspace has too many CK3 projects in it, but I'm not sure if this contributes to it. Does having more CK3 files in a workspace (without opening) them increase RAM usage? My workspace includes:

- base game's game directory
- my mods
- mods that I have compatibility patches for
- mods that my mods depend on

Another possible culprit is that many of my event files are autogenerated via a python script, so I have like 20k line files that should be excluded from processing. Is there a way to mark files or directories as excluded from indexing?
