Hi andras, wow that is getting large!

I hope that you might be able to post some screenshots of your project here? Maybe after it is complete...

I would like to add an XRef function in the future, but it will involve a lot of changes to many basic mechanisms such as display and selection, so it has a pretty high difficulty factor for me to add, that makes me uncertain of when I will be able to accomplish it.

Maybe you are already doing this, but one tip to reduce memory use now is to adjust your display settings to make a coarser display mesh.

That's under Options / View / Meshing parameters. Switch "Mesh angle" to 20 or 25 degrees, and uncheck "Add detail to inflections", if you have not already done so and that will probably help to reduce memory consumption.
