I think it would be an amazing addition to have config options to disable or enable WAILA/TOP features, for example:
-Log count on campfire
-Burn times
-Fuel capacity

I think these should be individually configured since for example - for a minimal UI I would display fuel capacity but hide number of logs on the campfire since you can easily see that just by glancing at it.

WAILA itself and some addons have added config options for individual fields and I find them to be extremely useful.
