Thanks for your feedback!
1. You can set the fontsize to 0 but I can also add a switch to make it easier
2. Customizing the gauges is a bit tricky. You probably want to try out some other plugins that are specialized on the gauges
3. Okay, I will add more font settings soon!
4. I can add settings for enemy's gauges, but individualizing for each member would be too heavy. Hope that's okay
