Thank you for your feedback Steve! We do plan to include some presets for UE5’s full release but the wildcard idea is something we definitely hadn’t thought of. I will bring this to the UX team to see if it’s something we can do and if so, I’ll implement it!
Have you tried Global Search? It works something like wildcard search - enter your query into the local search bar then click the button beside it to see all cvars that match your search terms, not just the ones you’ve added. Then you can add specific ones either by clicking the star beside each cvar or by simply changing the values which will add them to your current preset.
