pure_corruptions & OwlOwl900 suggest to add a panel in the settings section where HUD elements can be shown/hidden, colors & sizes changed, new crosshair options, etc.
My developer response: Excellent idea, I intend to add configuration options in the version to be released at the end of February 2022

jennyminecraft2 suggests to add an option to change the cursor/crosshair, they also report a bug where the default ammo counter is still showing.
My developer response: I chose the dot cursor because it was minimalist and unobtrusive initially, I will add additional crosshairs and the ability to use the default crosshair in the update to be released at the end of February 2022. I will also double check the default ammo counter on different conditions, but I do not believe that this is an issue internal to my addon.

Praecurs0r suggests to make the EKG more like the Resident Evil HUD with different colors based on status.
My developer response: I had a look at that HUD, will probably be shooting for the March release because there are other visual overhauls that I would like to make. When I do implement these new colors and visual enhancements they will be configurable through the settings panel that I will be adding in February of 2022.

Timmy Tip-Toes suggests to have the ability to have the HUD without the EKG.
My developer response: I will add the ability to remove HUD elements at the end of Feb. 2022. See above.
